Is the size of the effect in any of these studies stated in your comments? I skimmed them but didn't see what I was looking for.

Or via non-paywalled links?

Thanks.

"Sledge designed the humanoids to help humanity and be invulnerable to human exploitation. However, he eventually realized that they had instead taken control of humanity, in the name of their Prime Directive, to make humans happy

...

No humans may engage in any behavior that might endanger them, and every human action is carefully scrutinized. Suicide is prohibited. Humans who resist the Prime Directive are taken away and lobotomized, so that they may live happily under the direction of the humanoids."

Presumably it was meant literally, but the term "charity shop collector" seems to have some other meanings as well which are interesting to me as a non-UKian speaker:

   - A provider of "a charity shop back-end as a service", which disposes of donations 
     received by charity shops.

     e.g. https://live.ctrgroup.co.uk/third-sector/textiles-collection/ 

   - A person who collects things purchased from charity shops.
     
     e.g. "Harding is an avid charity shop collector, especially of sad and neglected 
     ceramic animals".
