I'm currently taking an introductory Russian class. I have been using Anki to memorize the vocabulary, and I do appear to know more vocabulary than anyone else in the class¹ except for one other individual. This individual has far surpassed everyone else in the class, in every area (grammar, vocabulary, etc). Several other students have made comments along the lines of "Geez, do you spend all your time studying?", and it had occurred to me that I should ask him what sort of study techniques he's using, and possibly try them out myself.

At this point, it occurred to me that this may be a reversal of Correspondence Bias. The other students and I assumed that his superior abilities were due to his own particular methods of studying, and not to any sort of innate language ability. And yet, I think it is at least likely that there are more people in the world with a natural talent for languages, than there are people who have found some kind of spectacular studying technique.

This is just a brief anecdote of a single life experience. Are there any systematic effects that we know of that work counter to Correspondence Bias?

¹ Data supporting this claim: in activities that we conduct inside the classroom, I have consistently remembered words that other members of the class do not, and it is very rare that a fellow student remembers a word from previous classes that I did not recall independently. Exceptions seem to have occurred mostly when a) it was not a word I put into Anki after class, or b) the other student is the individual I mentioned in the post.
