Final answer:
A playful person is most likely to convince a group to play strip poker, as their outgoing and less inhibited nature aligns with suggesting such a game, despite conservative sexual attitudes in the U.S.
Step-by-step explanation:
When considering who is most likely to convince the group to play strip poker, we need to think about personality traits and social attitudes. Typically, a more playful person is likely to suggest such a game because it aligns with their outgoing and less inhibited nature. On the other hand, individuals who are conservative or reserved are less likely to propose playing a game that's associated with risk and potential embarrassment.
Asch's study on conformity might suggest that in a group setting, people might agree to play if they have the support of others, but this is separate from who would initiate the game. Looking at the broader context of sexual attitudes especially in the U.S., which are considered conservative compared to most Western societies a bolder and playful individual would still be the key influencer in persuading the group to engage in a game like strip poker, as their personality overcomes social inhibitions that might discourage such activities.
