Systemizing is a term that is part of the empathizing–systemizing theory by Simon Baron-Cohen.
Systemizing
Systemizing is the drive to analyze or construct systems.[1]The systemizing quotient: an investigation of adults with Asperger syndrome or high–functioning autism, and normal sex differences According to Baron-Cohen’s research, the systemizing mechanism is set too high in autistic people. As a result, they can only cope with highly lawful systems, and cannot cope with systems of high variance or change (which includes “the social world of other minds”), and they appear change-resistant.[2]The hyper-systemizing, assortative mating theory of autism This strong inclination towards systemization is what is called hyper-systemizing.
Hyper-systemizing
Hyper-systemizing does not only denote rigidity and inflexibility, however, as it also predisposes individuals to show particular talents, and is part of the cognitive style of autistic people.[3]Talent in autism: hyper-systemizing, hyper-attention to detail and sensory hypersensitivity
The hyper-systemizing theory argues that the excellent attention to detail is directed towards detecting ‘if p, then q’ rules (or [input–operation–output] reasoning). Such law-based pattern recognition systems can produce talent in systemizable domains.

I think this arises to me in my life more with teaching styles. If it’s a bunch of random details that I then have to figure out the correlations and overall “system” from, then it takes much longer to learn. Whereas, if it is taught such that it’s framed out first, and then filled in, I can easily categorize and file everything in my brain for easy fast retrieval later. And actual full comprehension of all the correlations and interconnections allows for interpolation between the original limited data points that others only remember (without conceptual comprehension). To me it’s all about the “system”, whether it’s taught that way initially, or I have to build it myself. Not sure what this means in regards to autism though personally. Figured it was worth a comment though.
