This problem is an easy one to solve. Implicit association tests are effective at discriminating pedophiles from non-pedophiles.

Have 'age of consent' set as a community norm (keep it legal folks!) and 'must score under community-assessed maximum tolerable score on the pedo-IAT' as a condition of moving in.

You'd be the first neighborhood association to take this sort of strong, invasive(?) measure for preventing child abuse in a close knit community, I don't think they do this in Celebration, Florida (or whatever the Disney World community is called)


Note, any implementation should also include eye tracking, or another analytic to detect a user looking away and clicking at a constant rate. Looking away and clicking to advance at random or at a constant rate is the only mechanism for defeating an IAT.

How do I apply for a slot in the house? I'm tired of living by the sword and would love to relocate to a tech hub but don't know anyone.

I am skeptical that the IAT can accurately detect pedophiles. The article is paywalled, so I can't say anything specific about it, but I can gesture in the general direction of the reproducability crisis.

The IAT is part of a somewhat widely used assessment of sex offenders, the Able Assessment, and is less invasive than penile plethysmography (ref1). Unfortunately, IATs have been shown to be unhelpful for identifying female child sex offenders, as their cognitive approach to offending is different from that of men ('I was coerced by a man/lonely and horny' vs 'entitled and attracted to the bodies of children') (ref2).

There is likely a false positive rate for an IAT, enough that it is relegated to the realm of polygraphy, and inadmissible in court...but I am not particularly concerned, as it is likely not large enough to render the test worse than random, and for a community like this, given that no additional discrimination will be applied beyond 'please live somewhere else', males in this specific, vulnerable community should be fine with submitting to an IAT. Given the 'male coercion' factor in female sex offenders, denying access to men who 'fail' the IAT would probably reduce the liklihood of female offending as well.

The reproducibility crisis is real, and most psychometric tests are lousy for a number of reasons, but it is possible to extract data that is useful, though not perfect, for making decisions. This is not a fire-and-forget solution to the problem, but in concert with normal behavior intended to reduce harm, it will hopefully help prevent the 'Rationalist Baugruppe' from devolving into a 'Rationalist Pitcairn Island'
