Ostrich effect

The ostrich effect happens when you deliberately try to avoid negative information or thoughts. A form of "if I don't think about it, it can't hurt me" thinking.

Wikipedia says that "the name comes from the common (but false) legend that ostriches bury their heads in the sand to avoid danger."

Examples:

• You aren't happy right now, but thinking about the meaning of your life is stressful and can make you regret your choices. So you decide not to think about it, believing it will solve the problem.
• You can feel your relationship going downhill, but it's scary to talk about it. So you try your best to ignore the bad signs.
• You've been spending a bit generously today, so you avoid looking at your bank account for the rest of the day.
