> If offered a Snickers, a Milky Way and an Almond Joy, participants would always choose the Snickers. But if they were offered 20 candy bars, including a Snickers, the choice became less clear. They would sometimes pick something other than the Snickers, even though it was still their favorite.<p>Just because something is your favorite doesn't mean it's rational to always choose it every time. Hot wings are my favorite food, but I don't eat them three meals a day to the exclusion of everything else. If there's a selection of 20 candy bars, possibly including ones you haven't tried before, I don't think it's irrational to try a new one since that might <i>become</i> a favorite. Even if it's one you already know, maybe you're just in the mood for coconut instead of peanuts at the moment. This seems like a poor way to measure irrationality.
I am asking this out of my ignorance.<p>I usually never read 'Psychology/Happiness/Depression/Mindfulness/Optimism/Anxiety/Loneliness/Child Psychology/Meditation' articles that have plagued HN recently.<p>Is neuroscience legit science or is it unfair to lump it with psychology.
