Sequential information presentation strengthens decision-making bias, favoring supporting evidence over conflicting data. This effect persists even when information requests are fixed, ruling out alternative explanations.

Area of Science:

  • Cognitive Psychology
  • Decision Science

Context:

  • Individuals exhibit a preference for information supporting their decisions.
  • Previous research indicated sequential information presentation amplifies this bias compared to simultaneous presentation.

Purpose:

  • To investigate the underlying mechanisms of enhanced confirmation bias under sequential information presentation.
  • To differentiate between decision commitment and information-seeking effort as explanations for the observed effect.

Summary:

  • This study manipulated information presentation (simultaneous vs. sequential) after a preliminary decision, fixing the number of information requests.
  • Results confirmed that sequential presentation led to a stronger preference for supporting information, regardless of the number of information choices.
  • This finding supports the decision commitment explanation and rules out the alternative of increased information-seeking effort.

Impact:

  • Provides robust evidence for the role of decision commitment in sequential information processing.
  • Informs understanding of cognitive biases in information seeking and decision-making.
  • Has implications for designing information environments to mitigate bias.
