As you burn fat, you’ll sometimes notice that the area where the fat used to be tends to take on a sort of “squishy” consistency. “Squishy” fat forms because, as fat cells are extracted and mobilized, the space where they once existed gets filled with water, making the area feel “softer” than normal. Sometimes “squishy fat” forms in places we can see it, and sometimes it forms more internally where we can’t. Sometimes it’s in huge pockets, and sometimes it forms at a microscopic level where you can’t see it or feel it. But the areas that were once filled with fat sit there, filled with water!
In a follow-up, Lewandowsky presented a scenario that was similar to the original experiment, except now, the Aboriginal was a hero who disarmed the would-be robber. This time, it was students who had scored lowest in racial prejudice who persisted in their reliance on false information, in spite of any attempt at correction. In their subsequent recollections, they mentioned race more frequently, and incorrectly, even though they knew that piece of information had been retracted. False beliefs, it turns out, have little to do with one’s stated political affiliations and far more to do with self-identity: What kind of person am I, and what kind of person do I want to be? All ideologies are similarly affected.
Studies of the Dunning–Kruger effect usually have been of North Americans, but studies of Japanese people suggest that cultural forces have a role in the occurrence of the effect.  The study Divergent Consequences of Success and Failure in Japan and North America: An Investigation of Self-improving Motivations and Malleable Selves (2001) indicated that Japanese people tended to underestimate their abilities, and tended to see underachievement (failure) as an opportunity to improve their abilities at a given task, thereby increasing their value to the social group.
