My pet peeve is those ergonomics pamphlets with, not pictures of actual humans, but cartoony illustrations of supposedly ideal posture. Sometimes not even with realistic proportions. Never a citation of any actual research, just platitudes that whoever wrote the pamphlet heard from their parents once or just came up with on the spot. Probably given out just to satisfy some lawyer or insurance company to reduce worker's comp liability issues, so who cares if it's science-based or beneficial in the slightest.
