Q & A
What is the Ambiguity Effect and how does it influence decision-making?
-The Ambiguity Effect refers to the tendency of individuals to avoid making choices when faced with ambiguous options or incomplete information. It influences decision-making by causing people to opt for options that are more certain or have clearer information available.
Can you explain the Assembly Bonus Effect and its impact on group performance?
-The Assembly Bonus Effect is a phenomenon where a group produces an outcome that is superior to what each individual could achieve alone. 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. It is relevant to astrology and fortune telling because it explains why people accept these practices, attributing personal relevance to broad statements.
How does the Birthday Number Effect influence an individual's preferences?
-The Birthday Number Effect is a subconscious tendency for individuals to prefer numbers that appear on their birth date. This preference is most pronounced for numbers over 12, indicating a unique connection between significant dates and numerical preferences.
What is the Name Letter Effect and how does it compare to the Birthday Number Effect?

How does the Diffusion of Responsibility affect group actions and the Bystander Effect?
-The Diffusion of Responsibility refers to the decreased sense of individual responsibility within a group, leading members to feel less accountable for their actions. This can contribute to the Bystander Effect, where individuals are less likely to offer help in the presence of others due to unclear responsibility and roles.
What is the Cheerleader Effect and how does it influence perceptions of attractiveness?
-The Cheerleader Effect, also known as the group attractiveness effect, is a cognitive bias where individuals are perceived as more attractive when seen in a group than when seen alone. This effect suggests that social context can enhance the perception of attractiveness.
Can you explain the Cocktail Party Effect and its relation to selective attention?
