Once again, it depends what they mean. What do they mean by 'collect information' and what do they mean by 'categories of things'. Because I like learning about things, I like going on research dives and learning odd bits of information. But I don't think I approach it in such a systematic way that this question suggests.

I checked against an extended version of the same test (AQ-50), and this question had some added clarification;

(e.g. types of car, types of bird, types of train, types of plant, etc.).

I could be interested in learning about any of those, but it would not be motivated by its belonging to the category. It would be if the particular car, bird, etc had some inherent interest, or was relevant to something else I was involved with

I think I Slightly Disagree

Bruh, "taxonomy" is one of my favorite words. Definitely agree.

I'm the least organised person I know

This question amuses me because if you was going to take it completely literally, which seems like a reasonable approach for someone that is autistic, then you would read this as do you collect information and store it in some way such as files on the computer or a database. Which no, I don't do that. But I do like to learn about lots of different things.

Information about categories of things

Does this mean, having an in-depth knowledge about a certain topic (category) - the 'special interest' question?

It doesn't look like 'do you like to categorise and structure things', or does it?

Slightly agree to the first: movie quotes, car makes and types, x86 CPUs of the 90s and early 2000s. Though I wouldn't call it special interest.

Agree to the second. Finding categories for a given set of items feels natural and makes life easier for me.

This question has always confused me to a degree. I often said that my knowledge is in narrow wells that are very deep, but I think that's just what being a specialist is.
