A meta-analysis assessed whether exposure to information is guided by
defense or accuracy motives. The studies examined information preferences in
relation to attitudes, beliefs, and behaviors in situations that provided
choices between congenial information, which supported participants'
pre-existing attitudes, beliefs, or behaviors, and uncongenial information,
which challenged these tendencies. Analyses indicated a moderate preference for
congenial over uncongenial information (d. = 0.36). As
predicted, this congeniality bias was moderated by variables that affect the
strength of participants' defense motivation and accuracy motivation. In support
of the importance of defense motivation, the congeniality bias was weaker when
participants' attitudes, beliefs, or behaviors were supported prior to
information selection, when participants' attitudes, beliefs, or behaviors were
not relevant to their values or not held with conviction, when the available
information was low in quality, when participants' closed-mindedness was low,
and when their confidence in the attitude, belief, or behavior was high. In
support of the importance of accuracy motivation, an uncongeniality bias emerged
when uncongenial information was relevant to accomplishing a current goal.
