I scored 19 on Systematizing quotient, but I do not feel this reflects my systematizing abilities: I am not interested in railway formations, maths, technology etc. However, in the areas I am interested in I systematize to a huge extent. I believe this quotient is biased towards a certain type of interest (technology, natural science) and not towards other kinds of systematizing, therefore I do not think this test is that reliable.
Empathy: not surprising my score is this low. I really struggle with conventional empathy, but I do have feelings and care about others, just not in the conventional way. Feel no empathy when someone cries, for example. Most people with AS score around 20 so mine was incredibly low. AQ: 34, in the autistic range, but only just. I have done these tests before and they show internal reliability, but not necessarily external reliability. My scores are always very consistent. I was diagnosed 4 years ago, but my diagnosis was based on far more than just these tests, which are only screening instruments.
