I remember reading something much like this in I am right and you are wrong by Edward de Bono, who as I recall wrote that we should try to hold on to the "I haven't made my mind up" state much longer than we do, and be prepared to say "I don't know" much more often than we do (I think he even proposed a new word we could use to answer questions with that meant we don't have a reason to think either way yet). This was about 15 years ago so I've probably mis-remembered.
I was a philosophy undergrad at the time, and when I asked my tutors about de Bono, they told me he was a vacuous 'self-help' nitwit I should ignore.
