5.

5. What important issue has arisen about the evidence that castrating sex offenders is effective in stopping their behavior?

Only males have been tested; we can’t get a clear picture unless females also are tested (by having their ovaries removed).

Only males from a particular culture and country were castrated; therefore, it’s hard to extend the evidence to other cultures.

In 100% of the cases, castration effectively stopped repeat offenses. The evidence is clear.

In some cases, castration actually increased the tendency to re-offend.

The evidence on repeat offenders is self-reported by the castrated offenders themselves.

Correct. (See section 24·8 Hormones can affect behavior.)

Incorrect. (See section 24·8 Hormones can affect behavior.)
