Through an extensive review of the literature, a research gap was identified concerning the knowledge around diversity and its impact on personality types and their influence on group performance. Previous literature revealed that diversity is a popular determinant for group composition, since it encompasses many different meanings and interpretations. Researchers would rather focus on easily measurable elements such as age or gender, but few studies have been conducted on deep-level diversity, such as personality traits or values. The aim of this study is to answer the research questions proposed concerning the effectiveness of homogeneous versus heterogeneous groups as well as the impact communication has on their performance. Through an analysis of previous studies and literature the research questions and hypotheses were formulated, and a methodology designed to answer them. The methodology used in this research was a variation of the Marshmallow Challenge. The groups were faced with two challenges. The first one was to build a 50cm-tall structure as quickly as possible, with a limited amount of material, including raw spaghetti, tape, rope and a marshmallow to test the stability of the structure. The second challenge was presented about one week later and involved the same materials, but the participants had to reach 70cm. Four teams of three were chosen. The personality tests had four possible outcomes: red, green, yellow, or blue. Each colour had specific characteristics and adjectives associated with it. The data collected revealed that the heterogeneous groups performed better overall. A slightly significant correlation was found between how well the teams performed and the words spoken per minute for the first experiment, but not for the second. The biggest limitation that hindered this study was the time pressure and limited sample size.
This thesis investigates the effect choice options in e-commerce applications have on consumers’ decision making. Previous research showed that a large number of options
can affect consumers negatively. However, the conditions for such choice overload are unclear. After reviewing the existing research, the amount of information (entropy)
contained in a choice set and individual differences were determined as possible influencing factors in an online environment. In a choice experiment, choice sets with
varying information loads and an assessment of the Big Five personality traits were used to test the impact of the two identified factors on choice avoidance behavior. Results from chi-square-tests and a logistic regression model suggest choice overload but without entropy having an effect. A logistic regression model revealed that extraverted consumers are easier overloaded. A low Neuroticism score was found to be related to less occurrence of a too-much-choice-effect. Consumers with a high Openness score on the other hand choose one of the presented options more often and were therefore less often
overwhelmed by the assortment. An interaction effect between personality and the amount of entropy was not found. These findings extend the research on choice overload and offer valuable input for marketers targeting consumers online.
