@korewatsumi yes, I read the whole thing. It explained how there were neurodevelopmental differences in pedophiles, child sexual offenders, and subgroups of each. It explained how there are genetic factors and that it has been found to happen in the lines of some families. None of this precludes conditioning.

The brains of taxi cab drivers have a significantly larger part of their spacial memory cortex. That didn't happen out of the blue, but by repeatedly using those parts of their brain to memorize places. Brain structure is affected by genetics, inputs, and environment.
