Without reading: the title is accurate either way. Ignorance, even if has nothing to do with stupidity, might be expensive. At least I consider myself an extremely, radically ignorant person and I can see sometimes, how or why this becomes expensive.
With reading: it's an interesting question, what's the definition of "avoiding truth". A political example: if I'm basically liberal (or communist, or anything), for instance, and stay so, more or less, despite its issues, then I'm avoiding truth by definition? Or only if I deny its issues?
Can't tell much about the market-specific stuff, though; I'm informed about the big events around the ecosystem mostly through you.
But it seems for me that you're right.
