When uncertainty in social contexts increases exploration and decreases obtained rewards

Area of Science:

• Decision-making and cognitive psychology
• Social cognition and behavior

Background:

• Decision-making involves exploration (seeking new information) and exploitation (using existing information).
• Exploration is well-studied in non-social contexts but less understood in social environments, which are inherently uncertain.

Purpose of the Study:

• To investigate how social uncertainty influences exploration behavior compared to non-social uncertainty.
• To examine whether providing social information can reduce exploration in social contexts.

Main Methods:

• Four experiments were conducted where participants searched for rewards in grid-based tasks.
• Tasks were framed as either social (real people distributing points) or non-social (computer algorithm/natural phenomenon).
• Experiments 3 and 4 manipulated the type of social information provided about the agents.

Main Results:

• Participants exhibited greater exploration and earned fewer rewards in the social context compared to the non-social context.
• Providing information about social relationships and group membership significantly decreased exploration.

Conclusions:

• Social uncertainty drives behavioral exploration, potentially hindering goal achievement.
• Social-cognitive strategies for uncertainty reduction can mitigate excessive exploration in social decision-making.
