Without any anecdote or something, there is nothing to discuss. I instinctively realized this back before I had given up, when all the articles written by foids said "just werk on yourself so you're worth more to us".
Still, I call Briffault's law into question, because it does not appear to apply to Chad. Women throw themselves at Chad's feet no matter how useless, smelly, poor, etc. he is. So if you looked at the slewed* bell curve of how foids rate men's physical attractiveness, Briffault's law has no effect on the 8/10 - 10/10 range, it does slightly modify the 5/10 - 8/10 range (where all the betabuxxers sit, hence they are betabuxxers) and below 5/10, it again practically has no effect.
In less elaborate terms:
- if you're pretty, your usefulness cannot be so low that your absolute attractiveness suffers
- if you're "average", your usefulness can modify your absolute attractiveness to qualify or disqualify you
- if you're "ugly", your usefulness cannot be high enough to raise your absolute attractiveness to qualifying levels
*Note: foids' judgement of your physical attractiveness is what counts as they are the gatekeepers, but it's far from fair or objective, as everyone knows.
