> Why follow the rules of some online survey? Logically you should do whatever provides you the maximum emotional benefit, regardless of what the rules say.

Why follow the rules of the game then? I used to cheat at many games both online and offline, some casinos think I "cheat" because I always count cards, I have an explicit gain by winning in all scenarios, as I either gain more satisfaction from winning or monetary output.

The same social consequences come from the online survey, i.e. I do collect information about who you are, further you do damage the quality of the data meant to fund/explore future decisions in all kinds of venues, e.g. social studies, politics, etc.

Online surveys are not valid research tool anyway, because of heavy selection bias.

As for giving bullshit answers on them, valid surveys have built-in protection measures. The amount of trolling in surveys has been measured this way; I've seen it refered to by at least one author as "Lizardman's constant", and it was consistently around 7% or such.

It's unlikely to be a constant amount. There have been, somewhat ironically, surveys about lying on surveys. One result is that people will indicate being more or less likely to lie, depending on the sort of question: https://www.bbc.com/news/blogs-magazine-monitor-29206289
