Non-confirmatory information can also be harder to deal with because it is usually framed negatively (e.g., it rained when we did not seed), and we sometimes have trouble conceptualizing negative assertions. Compare, for example, how much easier it is to comprehend the statement “All Greeks are mortals” than “All non-mortals are non-Greeks.” Thus, one would expect confirmatory information to be particularly influential whenever the disconfirmations are framed as negations. The research literature strongly supports this prediction.
We have trouble conceptualising negative assertions.
