Or putting it differently:

• One thing is to operationally avoid gaining certain data at a certain moment in order to better function overall. Because we need to keep our attention focused.

• Another thing is to strategically avoid gaining certain kinds of information that could possibly lead us astray.

I'd guess most people here agree with this kind of "self-deception" that the former entails. And it seems that the post is arguing pro this kind of "self-deception" in the latter case as well, although there isn't as much consensus — some people seem to welcome any kind of truth whatsoever, at any time.

However... It seems to me now that, frankly, both cases are incredibly similar! So I may be conflating them, too.

The major difference seems to be the scale adopted: checking your email is an information hazard at that moment, and you want to postpone it for a couple of hours. Knowing about certain truths is an information hazard at this moment, and you want to postpone it for a couple of... decades. If ever. When your brain is stronger enough to handle it smoothly.

It all boils down to knowing we are not robots, that our brains are a kludge, and that certain stimuli (however real or true) are undesired.
