In an earlier post, I mentioned how I had the completely wrong idea about what in America is referred to as ‘pickles’. In a comment on that post, Crip Dyke made an interesting point that made me reflect on the question of ignorance.
[W]hen one has a reputation amongst one’s friends for being knowledgeable, one has more to lose by revealing that one has been making such an error … and thus the fear of this may very well be heightened for people who have a reputation amongst their circle as knowledgeable. Thus I sometimes wonder if my fear of making a clueless error is just my vanity in disguise. (though, of course, there do exist independent reasons to want to avoid error)
