1. Introduction
In order to survive in the current competitive environment, both private and public organizations are constantly looking to reach organizational effectiveness and efficiency; however, the achievement of these results depends on organizational agents’ level of effectiveness and efficiency (
Inuwa 2016) and how good they are at making decisions (
Simon 1947). According to the established literature, organizational agents’ ability to make successful decision-making processes mainly relies, on the one hand, on the organizational environment (
Wu and Lee 2016) and, on the other hand, on individual characteristics, such as emotions (
Cristofaro 2019,
2020) and personal traits (
Paniccia 2002;
Cristofaro 2016,
2017a;
Busic-Sontic et al. 2017). Among personal traits, the Core Evaluations (CE) (
Judge and Bono 2001), namely the evaluations that individuals make about others, the world, and themselves (in this last case, we mean core self-evaluations, CSE), are those that have been receiving increasing attention from behavioral strategy scholars (
Hiller and Hambrick 2005;
Powell et al. 2011), due to their ability to predict job performance (
Judge and Bono 2001) and to explain some facets of decision-making processes (
Hollenbeck et al. 1988;
Judge et al. 1998;
Silvester et al. 2002).
However, despite previous studies hypothesizing that managers with high values of CSE (assimilated to hubris; see
Hiller and Hambrick 2005) are intuitive thinkers, beyond any doubt of their capacities and that they significantly lead to positive results for their organization (e.g.,
Claxton et al. 2015), no one has empirically investigated these assumptions. Studies have investigated some trait pillars comprising CSE, such as self-esteem, in relation to decision-making process variables; however, there has not been any investigation at the group level of analysis (e.g.,
Jordan et al. 2007), even though the level is a common working unit within organizations (
Koontz et al. 1980). Filling this gap, which can be substantiated by the research question: “
how do high Core Self-Evaluations influence team decision-making processes?”, is relevant also from a practical point of view due to the fact that personnel selection managers have been found to be biased and oriented towards selecting people that show high levels of CSE (
Cristofaro 2017b).
In order to answer the aforementioned research question, a sample population of 120 graduate students was collected—divided into groups of four—to take part in a simulation game and they were asked to make decisions, in groups, acting the role of General Manager of a small-sized manufacturing firm. Tests aimed at identifying the CSE and intuitive/reflecting thinking approach of participants were administered; moreover, the performance resulting from their decision-making processes and their estimation of reached results were collected. Results of the work show a partial verification of the hypothesis that a high level of CSE leads to an intuitive decision-making process and a high level of performance; meanwhile, they are totally supportive of the positive relationship between a high level of CSE and being victim of overconfidence bias. Yet, results show that the average level of CSE is preferable to balance intuitive and reflective thinking as well as avoiding overconfidence bias and reaching the best performance possible.
Evidence produced really helps to understand the implications of the CSE trait variable for decision-making processes within organizations. Accordingly, prior literature provides evidence of the misattribution in considering a positive value of a high level of CSE as beneficial for performance (
Judge et al. 2009;
Judge and Hurst 2008). Yet, to the best of the authors’ knowledge, this is the first study investigating the CSE trait variable at the group level—apart from also being the first to investigate, in depth, its implications for organizational decision-making processes. These results suggest that, in terms of practical implications, human resource managers track the CSE level of each individual within organizations and suggest composing teams accordingly to achieve better decisional and organizational performance.
The paper is structured as follows. First, readers of Administrative Sciences are informed of the basic assumptions behind the Core-Self Evaluation construct and concepts at the basis of decision-making processes. Second, the development of the hypotheses is provided. Third, the methodology is shown with details about the research context, i.e., the simulation game, as well as the data collection and analysis procedures. Fourth, results of the three one-way Analysis of Variance implemented to test developed hypotheses are shown. Fifth and last, discussion of the results in light of prior literature as well as implications for theory and practice are given.
3. Hypotheses’ Development
Hayward and Hambrick (
1997) used intermediary indicators of hubris, which captured a variety of presumed circumstantial and personality aspects, demonstrating the crucial need for a psychometrically grounded and approved construct for studying the extraordinary self-confidence in executives. Later,
Hiller and Hambrick (
2005) considered hyper-CSE to precisely measure that construct; the upper limit of CSE may be considered as an accurately certified ‘hubris factor’. In sum, analysis on the conceptually comparable ideas of executive narcissism and hubris led our understanding of high-CSE executives. Especially, a significant level of CSE may precisely coincide to what is colloquially pointed out as hubris. Hubris, or hyper-CSE, has a great connection with intuitive thinking, as advanced by
Claxton et al. (
2015) who claimed that hubristic leadership is usually connected with intuition.
Jordan et al. (
2007) examined both intuition and the correlation between tacit and explicit self-esteem, one of the four fundamentals of CE, testing whether the grasped effectiveness of the intuition increases the congruity between tacit and explicit self-esteem. It appeared that individuals who persistently consider their instinct as predominant are more inclined to tacit and explicit self-esteem. Contrarily, individuals with moderately intuitive thinking inclination had a negative correlation between tacit and explicit self-esteem, proposing that they may overcorrect their explicit self-views. Translating the above mentioned at the collective level:
Hypothesis 1. Teams with high CSE are more intuitive compared to teams with low and average CSE.
Kramer et al. (
1993) explored the influence of motivational and emotional mechanism on negotiator judgment. They considered whether positive disposition and the inspiration to preserve high self-esteem lead the negotiator to be overconfident and to make excessively positive self-evaluation. A research test using dyadic bargaining was organized to test this hypothesis and outcomes supported Kramer’s forecasts that high self-esteem and positive attitude influenced negotiators’ determination and confidence preceding to negotiations, as well as their post-negotiation assessments of conduct. Similarly,
Baumeister et al. (
1993) analyzed the inclination for individuals with high self-esteem to judge themselves about their ability to make commitments; it resulted that subjects with a high level of self-esteem end up setting inappropriate, risky goals that were beyond their capabilities, so they finished with smaller rewards than subjects with low self-esteem. Yet,
Zacharakis and Shepherd (
2001) analyzed whether Venture Capitalists (VCs) are victims of overconfidence when evaluating firms’ potential, as well as the elements surrounding the choice that lead to overconfidence. The outcomes of their experiment demonstrated that VCs are undoubtedly overconfident (96% of the 51 VCs showed a critical level of overconfidence), which negatively influences VC’s decision efficiency. In particular, they found that when VCs are familiar with decision-making processes, such as the evaluation of venture success, and the structure of the data included that choice, they resort to automatic information processing; they rely on limited information, leading them to fall victim to overconfidence. This has also been developed by a few later articles on the relationship of General Managers’ dispositions and their capacity to carry on sustainability practices; specifically,
Abatecola and Cristofaro (
2019) demonstrated, through a literature review, that CEOs with large CSE are mostly certain in their analysis in carrying out unsustainable business practices. Translating the above mentioned at the collective level:
Hypothesis 2. Teams with high CSE are more inclined to be victims of the overconfidence bias compared to teams with low and average CSE.
As already mentioned,
Hiller and Hambrick (
2005) found that a high level of CSE is close with what is routinely called “hubris”. They have also explored the connections between executive distinctiveness and factors of organizational technique, structure, and execution; from that, they anticipate that hyper-CSE managers will display this characteristic in their work attitude. They state that executives with large CSE are beyond any questioning of their skills, and they consider significantly that the application of their competences will bring positive outcomes. CEs outlined that people who are extraordinarily beyond any doubt in their claim abilities, and make continued effort over time towards their targets, are persuaded to get compelling results in their career by picking up essential compensations and important roles in society. Yet, the link between CSE and performance has also been proved to work when judging candidates for job vacancies. In particular,
Cristofaro (
2017b) found, through a laboratory experiment involving personnel selection executives, that candidates who are perceived to have high CSE are also those that will achieve great performance; in contrast to low CSE candidates that are perceived as low performers. Translating the above mentioned at the collective level:
Hypothesis 3. Teams with high CSE reach higher positive performance compared to teams with low and average CSE.
5. Results
To verify whether teams with high CSE are more inclined to intuitive thinking rather than average and low CSE groups (H1), a one-way ANOVA was firstly implemented considering the different CSE clusters (low, average, high) and their groups’ results on the CRT test.
As shown in
Table 1, there was a statistically significant difference between groups as determined by the one-way ANOVA (F(2,27) = 80.510,
p = 0.000). A Tukey post hoc test, shown in
Table 2, revealed that high CSE groups were more inclined to the average CSE groups for intuitive thinking (−4.2 right answers compared with them;
p = 0.00), but they were equally inclined to intuitive thinking with respect to low CSE groups (
p = 0.964) (
p = 0.989). So, H1 is
partly verified.
In order to verify whether teams with high CSE are more inclined to be victims of the overconfidence bias compared to teams with low and average CSE (H2), a one-way ANOVA was implemented considering the different CSE clusters (low, average, high) and their average teams’ estimation of performance.
As shown in
Table 3, there was a statistically significant difference between groups as determined by the one-way ANOVA (F(2,27) = 295.962,
p = 0.000). A Tukey post hoc test, shown in
Table 4, revealed that high CSE groups were more inclined to the average CSE groups (+
$12,000 of net worth overestimation compared with them;
p = 0.00) and low CSE groups (+
$30,000 of net worth overestimation compared with them;
p = 0.00) to be victims of the overconfidence bias. So, high CSE groups were the ones that overestimated their performance more than other CSE groups, while low CSE groups were the ones that overestimated their performance least compared to other CSE groups. So, H2 is verified.
In order to verify whether teams with high CSE reach higher positive performance compared to teams with low and average CSE (H3), a one-way ANOVA was implemented (see
Table 5) considering the different CSE clusters (low, average, high) and their average teams’ actual performance in terms of net worth.
As shown in
Table 5, there was a statistically significant difference between groups as determined by the one-way ANOVA (F(2,27) = 113.384,
p = 0.000). A Tukey post hoc test, shown in
Table 6, revealed that high CSE groups reached greater performance than low CSE groups (+
$50,800 of net worth overestimation compared with them;
p = 0.00), but they reached lower performance than average CSE groups (who, on average, gained +
$53,000 of net worth). So, H3 is partly verified.
6. Discussion and Implications
This work offers a contribution to the debate about how CSE influences team decision-making processes. In order to do so, the research has been based on the analysis of four variables: CSE, intuitive/reflective thinking, overconfidence, and performance. Accordingly, three hypotheses have been formulated and tested—through one-way ANOVA and Tukey post hoc tests—on a sample population composed of 120 students while taking part in a simulation game in which they were asked to make decisions, in groups, acting in the role of the General Manager of a small-sized manufacturing firm.
The results only partially verified the first hypothesis. In fact, both teams with high and low CSE are equally inclined to intuitive thinking. This aspect deserves particular attention; indeed, if it is true that previous literature on the topic (e.g.,
Hiller and Hambrick 2005;
Jordan et al. 2007;
Claxton et al. 2015) has already recognized the existence of a link between high levels of CSE and intuitive thinking, it is surprising to see that also groups with a low level of CSE have the same predisposition to intuitive thinking. Therefore, the high self-consideration by individual/groups seems to lead to the same consequence of having low self-consideration: being inclined to intuitive thinking. Despite that, this result can be considered in line with the study of
Rudolph et al. (
2009) (see also the similar one by
Cristofaro 2016) who found, through a computer-based simulation on data collected in clinical decision making, that the decision-making behavior that usually leads to wrong decision options is usually carried out by people that take too little, or too much, time to make a decision. These results complete these studies by providing the explanation at a personal trait level of why this different decision behavior occurs. The results totally confirm the second hypothesis. In fact, teams with a high CSE level were more predisposed to both average and low CSE groups of falling into the overconfidence trap. This is perfectly in line with previous literature on these topics (e.g.,
Baumeister et al. 1993;
Kramer et al. 1993;
Zacharakis and Shepherd 2001) and highlights how high CSE groups, overestimating their capabilities, tend to “destroy” their decision-making ability (
Abatecola et al. 2018;
Abatecola and Cristofaro 2019). Lastly, results only partially verified the third hypothesis. In fact, if it is true that high CSE groups reached higher positive performance compared to low CSE groups—as already demonstrated by previous researches (e.g.,
Hiller and Hambrick 2005;
Cristofaro 2017b); it is also (surprisingly) true that average CSE groups reached more positive performance compared to high CSE groups. By linking the results of the test of the first and third hypothesis, it emerges that groups with a high level of intuitive thinking (corresponding to the ones having high or low CSE scores) are not the best performers in decision-making terms. This result contributes to the debate on the consequences of intuition in management decision making. In particular, it supports a stream of prior results highlighting that intuitive thinking leads to poor quality of decisions (
Elbanna et al. 2013), which consequently leads to poor firm performance (
Goll and Rasheed 1997). This happens, as suggested by
Elbanna et al. (
2013), because intuitive decision makers are impatient with routine or details—i.e., they have a poor systemic search for information—and are pushed, by their nature, to quickly reach conclusions and to ignore negative problems. However, despite reinforcing this stream of works, another important one has found a positive relationship between intuition and firm performance; such as in developing technologies, sizing new opportunities, and providing effective responses to crises (
Bullini Orlandi and Pierce 2020). What is the determinant for the success of intuitive thinking seems to be, according to
Bullini Orlandi and Pierce (
2020), the dynamicity of the industry environment; indeed, in cases of highly dynamic and turbulent environments with the presence of real-time data, intuitive thinking is preferred rather than the reflective one. In sum, despite the confirming results of this work in substantiating a negative role of intuitive thinking in decision making, the rapid change of contextual and environmental variables can lead to positive effects of intuitive thinking—in line with the ecological rationality approach (
Gigerenzer and Brighton 2009).
Thanks to this work, the results provided extend those of cited and discussed contributions, offering a more solid base for the highlighted assumptions by providing an empirical assessment of an established personal trait variable, CSE. Indeed, cited studies only assumed this relationship looking at one of the four pillars of the CSE, such as self-esteem (e.g.,
Kramer et al. 1993;
Baumeister et al. 1993;
Jordan et al. 2007), or by providing a theoretical explanation (
Hiller and Hambrick 2005;
Abatecola et al. 2018;
Abatecola and Cristofaro 2019). Moreover, this is the first study that investigates the outlined relationship at a group level, practically overcoming the limits of the others that considered only the individual level of analysis.
Based on the exposed results, some important managerial implications can be derived for practitioners, especially the younger ones (Millennials) with a similar age to the sampled students. Firstly, as CSE is a personal trait, it is not possible to suppress it in an absolute sense; or, at least, it is very difficult in a short or medium range timescale. However, practitioners can reduce its value to an average by composing an ad hoc team. They can, in practice, bring together people with different CSE levels so that the CSE average will result as “acceptable”—namely, the score of their CSE needs to be between −8 to +8 points—there will be a balance between intuitive and reflective thinking in the team and, thus, the possibility of avoiding the overconfidence trap and the opportunity of achieving satisfactory performance. Thus, it is fundamental that human resource managers track the CSE level of each individual within organizations. In this way, they also have the possibility of appropriately suggesting—to department or unit heads—the “best team composition” to achieve better decisional and organizational performance. At the same time, if an organization needs to quickly respond to internal or external pressures, such as identifying a commercial strategy to counteract a sudden, huge price cut of a competitor, composing teams of individuals with exclusively high or low CSE levels can be beneficial for the production of intuitive (and quick) responses.
Despite the rigor with which the experiment was conducted, this study has some limitations, which also represent fruitful starting points for future researches on these topics. Firstly, the sample population is composed by students, which means that most have little or no work experience. A second and connected limit is determined by the fact that the experiment was conducted during course lectures; therefore, participants applied their strategies in an environment in which they were comfortable. In particular, they acted without being subjected to external pressure and this could have biased, for example, their risk orientation—with obvious consequences on the potential performance that would have been attained with another ‘purer behavior’. A third and no less important limitation of this research arises from the fact that some variables have not been controlled, for example, work experience and risk orientation, although in real life they obviously affect the behavior and attitude of managers in managing situations and acting upon them. Finally, a fourth and last research limit results from the structure of the platform provided to the students. Indeed, like all simulation games, there are limitations about the representation of all the variables that are played within real world choices. In sum, despite the fact that respondents’ decisions have been implemented (and tracked by the researchers) within a very well simulated environment (i.e., the simulation game), which is better than paper-based cases, sampling managers in real life situations would be necessary for extending the generalizability of these results. Future research can surely solidify the results of this work by avoiding the outlined limits; moreover, following
Abatecola et al. (
2018), future research avenues could investigate if there are other cognitive distortions (e.g., self-serving, emotion and cognition collision) in managerial decision making—in addition to overconfidence—that are linked to and influenced by CSE. Yet, the results of this work should be highly considered by scholars that want to deepen the antecedents of intuition and its outcomes in strategic decision-making (see
Elbanna et al. 2013). In particular, future research can test whether trait variables—CSE above all—have more weight than contextual and environmental ones in determining the thinking style of decision makers. Last but not least, the link between CSE and performance could be deepened also by looking at the emotional answers that high, average, and low CSE groups have when facing some decisional situations. These can reinforce the debate and operationalization of intuitive thinking which, nowadays, still does not take the role of emotions in substantiating intuitive answers into very high consideration.
The originality of this work is threefold. Firstly, we are not aware of any study that has investigated the influence exercised on decision-making processes by CSE in relation to reflective/intuitive thinking, overconfidence, and performance. Secondly, these relationships have always been investigated at the “individual level”. However, most of the tasks in an organization are performed at team level and decisions are rarely made individually; thus, this study adopts a “team/group level” to evaluate the importance and the influence of these aspects on organizations. Thirdly and lastly—despite the limitations previously exposed—this paper gives evidence of what really happens within organizations without resorting to case studies but, instead, is shown through the direct participation of individuals—i.e., students—acting as General Managers.
