Partially to help reduce the typical mind fallacy and partially because I'm curious, I'm thinking about writing either an essay or a book with plenty of examples about ways by which human minds differ. From commonly known and ordinary, like differences in sexual orientation, to the rare and seemingly impossible, like motion blindness.
To do this, I need to start collecting examples. In what ways does your mind differ from what you think is the norm for most people?
I'm particularly interested in differences - small or large - that you didn't realize for a long time, automatically assuming that everyone was like you in that regard. It can even be something as trivial as always having conceptualized the passing of years as a visual timeline, and then finding out that not everyone does so. I'm also interested in links to blog posts where people talk about their own mental peculiarities, even if you didn't write them yourself. Also books and academic articles that you might think could be relevant.
Some of the content that I'm thinking about including are cultural differences in various things as recounted in the WEIRD article, differences in sexual and romantic orientation (such as mono/poly), differences in the ability to recover from setbacks, extroversion vs. introversion in terms of gaining/losing energy from social activity, differences in visualization ability, various cognitive differences ranging from autism to synesthesia to an inability to hear music in particular, differences in moral intuitions, differences in the way people think (visual vs. verbal vs. conceptual vs. something that I'm not aware of yet), differences in thinking styles (social/rational, reflectivity vs. impulsiveness) and various odd brain damage cases.

A few things:
1) I seem to have a much better long-term memory than short-term memory. I always seem to be able to remember details of events long ago based on just small reminders. Yet in daily life I always find myself having to ask people to repeat an explanation or list becuase it just "vanishes" from my mind shortly after I hear it. I'm always having to stop and write stuff like that down.
2) I automatically try to "plug in" everything I learn into the rest of my understanding: see how it relates to other topics, what inconsistencies there might be, etc. This makes it easier for my to pass on understanding to others, as I just follow back the "inferential path" in my mind and then trace it out in the person I'm explaining it to.
It's led to frustration in that I've long assumed everyone else represents knowledge this way, so when they give bad explanations, it's because they're not even trying, but typically, it turns out they haven't connected the subject matter as deeply in their own mental representations. (Yes, I've talked about this before, didn't dig up the links.)
3) Whenever given some objective or criteria, I immediately think of how to fail it in the worst way possible. For example, if I'm told not to mention Bob's balding hair to him, I immediately think of the most horrible way to do so. (Naturally, I don't act on these ideas, but my mind sort of defaults to thinking about them to fill the empty space.)
Thanks for doing this, I've been wanting to gather this information as well, perhaps later come up with a standard checklist so people can find out what kinds of mentalities they have are abnormal.
I have a tendency that's possibly related to your #3: when someone makes a factual assertion I immediately consider its negation as a distinct possibility. That is, the negation becomes more available to me, and therefore in some sense more plausible. Else, why make the assertion in the first place?
