Can you explain the Assembly Bonus Effect and its impact on group performance?

The gain in performance is due to the synergy and complementary skills of the group members, leading to a collective effort that exceeds individual capabilities.

What is the Barnum Effect and why is it relevant to astrology and fortune telling?

The Barnum Effect is a psychological phenomenon where people give high accuracy ratings to vague and general descriptions of their personalities, believing they are tailored specifically for them.
