“A lot of people enjoy drinking, and they don’t like to be told that something they really enjoy is bad for you,” Gakidou says.

Replace drinking with almost anything that people enjoy and that's a pretty good summation of human behaviour. There's a negative version too:

"People don't like to be told something they don't enjoy is good for them."

Variants include the someone else version.

"People really don't like to be told that something they enjoy is bad for someone else, or to be put at an inconvenience for the greater good, no matter how mild that inconvenience is."
