Abridged article/selected quotes by me:

Abstract: Males tend to cooperate with physically attractive females without careful evaluation of their trustworthiness, resulting in betrayal by the female. In this experiment, healthy male participants made risky choices (whether or not to trust female partners, identified only by photograph, who had decided in advance to exploit the male participants). The results show that trusting behaviour in male participants significantly increased in relation to the perceived attractiveness of the female partner, but that attractiveness did not impact trusting behaviour in the minocycline group.

Introduction:

In an economic exchange, attractiveness in a female increases sexual arousal in a male...without careful evaluation of her trustworthiness

This is normal, as we are all going for beauty when looking to bang a girl

While these traits should be adaptive in terms of mate-choice, experimental studies have shown that they also affect decisions in social and economic exchange

In other words, although thinking of a girl's tits & ass is good for mating purposes, it basically is a shitty strategy in any other social situation with women, as they will screw us over.

So what's with this drug?

Recent studies with human subjects show that minocycline, a commonly used tetracycline antibiotic, may facilitate focus on appropriate environmental cues for social decision-making

Okay, that's good...but this is interesting:

Minocycline is also known to improve symptoms associated with psychiatric disorders such as schizophrenia and depression

Anyone else find it funny that the same drug used to inhibit the effects of both psychiatric disorders is also effective in protecting against the "honeytrap"? No wonder husbands say that their wives drive them crazy!

Method: Here's a flowchart of the "economic game" they played.. Very easy to understand.

The amount of money given was expected to function as a behavioural measure of the trust the male participant has in the female partner. In this experiment, male participants had no information about the female partner except for a photograph.

Results: Bar graph of the results

  • Placebo and Minocycline groups gave the same amount of money to the non attractive female

  • Placebo group gave larger amounts of money when the partner was more attractive

  • Minocycline group did NOT give more money when the partner was more attractive

Conclusion:

The authors mainly focuse on Minocycline as a drug and it's usefulness in the future.

But I think the RP lining in this study is that the same drug that improves schizophrenic symptoms also was shown to improve resistance to irrational thinking and the "honeytrap". If our brains process both of these the same way, then that has implications for how to attack manipulative social situations in the future.
