And this has consequences in adulthood, where the notion of expertise can mean struggling to discern when introspection is the best strategy. The researchers who carried out this study suggest that the distorting effect of reason-giving is most likely to occur in situations where people aren't experts – most of the students who took part in the study didn't have a lot of experience of thinking or talking about art. When experts are asked to give reasons for their feelings, research has found that their feelings aren’t distorted in the same way – their intuitions and explicit reasoning are in sync.
You might also see the consequences of this regularly in your line of work. Everybody knows that the average business meeting will spend the most time discussing trivial things, an effect driven by the ease with which each member of the meeting can chip in about something as inconsequential as what colour to paint the bike sheds. When we're discussing complex issues, it isn't so easy to make a contribution. The danger, of course, is that in a world which relies on justification and measurement of everything, those things that are most easily justified and measured will get priority over those things which are, in fact, most justified and important.
