>When it comes to rating movies and shows, stars reflect the preferences that people want to have, rather than how people actually behave. Todd gave the example of users giving 5 stars to a documentary but just 3 stars to an Adam Sandler movie that they watched over and over again. “What you do versus what you say you like are different things,” said Todd."

There's a reasonable objection to this behavioral definition of "like", which is that it doesn't actually make people's lives better, it just fills them with more compulsive behavior. It's not necessarily "irrational" to wish you were more patient, or to want to ask Netflix to show you useful things rather than useless fluff. That you occasionally betray your stated goals does not mean you should be denied the right of self-definition.

In other words, what people say they like is more important, to me at least. See eg "Thinking Fast and Slow" by Kahneman.
