## Appendix A Factual Description of the Dataset  
Only 50 contestants were women, while the rest were men. The most-represented age group was the third (from ages 25 to 34) group, accounting for 36.8% of the contestants. This was followed by the fourth (from ages 35 to 44) age group, which made up 26.3% of the contestants, while the first (up to 18 years of age) and seventh (older than 65 years of age) age groups were the least represented, with 0.6% and 1.8% of the contestants, respectively (labeled according to Table 2). A significant portion of contestants (61.4%) had completed the seventh (i.e., master's level university study) level of education. Another 19.3% had completed the sixth (i.e., bachelor's level university study) level of education, and 12.3% the fourth (i.e., high school diploma) level. Labels depicting the levels of education are presented in Table 3. Regarding the fields of work, the most represented were the social sciences (5) and humanities (6), followed by the technical (2) and natural (1) sciences, and then the biomedical and health (3) sciences (labeled according to Table 4). Artistic and interdisciplinary fields were represented by less than 5% of the contestants. The chasers knew about 59.6% of the contestants beforehand. Approximately 53.8% of the contestants intended to spend their winnings on leisure (3), while only 5.3% cited education or donation (4) as their primary purpose (labeled according to Table 7).  
As many as 40.4% of the contestants came from the City of Zagreb (1), followed by 33.3% from Adriatic Croatia (4), and 16.4% and 9.9% from Northern (2) and Pannonian (3) Croatia, respectively. The majority of the contestants came from large cities (1), while only 14% were from smaller cities (2). The labels used are derived from Tables 6 and 5, respectively.  
Regarding the selected offer, in the sixth age group (from ages 55 to 64), as many as 70% of the contestants opted to compete against four chasers. Notably, 33.3% of the contestants from the oldest age group (\(\geq\)65 years) selected three chasers, whereas only 8.9% of the contestants from the fourth group (from ages 35 to 44) made the same choice.  
On average, more educated individuals tended to select offers with fewer chasers and less prize money compared to those of contestants with lower educational levels. As shown in Figure 11, the frequency of selecting the offer with three chasers increased, while that of the selection of the offer with five chasers decreased with higher educational levels, with exceptions in groups 2 and 8, which are highly underrepresented, with only one and four samples, respectively. On the left-hand-side graph in Figure 11, the dataset's imbalance is evident because of the significant dominance of the seventh education group (master's level university study).  
spring part of the second season, the percentage of the contestants selecting five chasers rose to 31.3%, while the number of contestants selecting three chasers dropped to only 31%. In the most recently aired segment at the time of the writing of this article (the fall segment of the second season), another shift occurred: 21.3% of the contestants selected the offer with three chasers, while only 15.4% selected the offer with all five chasers.  
The contestants from the biotechnological science and art fields were the most successful ones, with 42.9% and 50% of the wins, respectively. The contestants with the lowest winning rates were those from the fields of biomedical and health sciences (22.2%) and humanities (25.8%).  
The contestants who came from small cities won in 37.5% of the games; those from middle-sized cities, 25.5%; and the ones from large cities, 32.3%. Adriatic Croatia had the most wins when considering the success relative to the number of contestants from that group (36.8%). Pannonian Croatia had the lowest percentage of wins, with only 17.6% managing to beat the chasers.
