WHY ARE PEOPLE WHO HUMBLEBRAG SO ANNOYING?

The definitive research on the topic remains a 2018 paper by psychologists at the University of North Carolina and Harvard Business School.

Only marginally less annoying is the humblebragger who deploys false modesty, such as "I don't understand why I keep getting hit on".

Whether it's light entering the retinas in your eyes, or sounds vibrating the hairs in your ears, it not only takes time for the data to arrive, but your brain then has to process it.
