Juggernaut law is the theory that the very most unattractive women (bottom ~10%) receive a surprisingly large amount of attention from men, and sometimes more attention than average attractiveness women. The name of the theory comes from the idea that a women's SMV is 'unstoppable' like a Juggernaut. A conclusion of this theory is that being horrendously ugly can actually be a good thing to femoids. Because of the increasing amount of men who aren’t good enough for any woman who is even a tiny bit attractive. This obviously isn’t the case for men, as described by female hypergamy.
A study from the popular dating app okcupid analyzed the phenomenon of the juggernaut law perfectly.
The study came up with this conclusion:
“When some men think you’re ugly, other men are more likely to message you. And when some men think you’re cute, other men become less interested. Why would this happen? Perhaps a little game theory can explain:
Suppose you’re a man who’s really into someone. If you suspect other men are uninterested, it means less competition. You therefore have an added incentive to send a message.
On the other hand, a woman with a preponderance of ‘4’ votes [out of 5], someone conventionally cute, but not totally hot, might appear to be more in-demand than she actually is. To the typical man considering her, she’s obviously attractive enough to create the impression that other guys are into her, too.” 
Pig woman experiment
The infamous “pig woman” dating experiment. proved that females can’t essentially be incels, since even the most deformed landwhale would get hit on by average looking dudes and even a tyrone. The experiment best highlights juggernaut law. The experiment was originally posted on the 'misc' subforum of bodybuilding.com and was later replicated by a lookism.net user. https://lookism.net/Thread-Pig-Woman-POF-thread
What’s the deal?
Males naturally have a higher sex drive (primarily caused by higher testosterone) and a desire to spread their unlimited sperm cells, juggernaut law states that men might feel they have a higher shot with a woman who’s plainly average, or even ugly. Juggernaut law has even been shown to be true, even for women who have deformities), because there are plenty of men who exclusively target very ugly women
In real life and betabuxxing
Even in marriage, a study in Spain concluded that:
“Being unattractive reduced the probability of mating for males by between 15 and 17 points, when compared to the more attractive group, and 10 points compared to those with an average attractiveness level. There was a statistically significant difference between the most attractive group and the normal group in favour of the former, which included education level, age and social class of origin.”
“Among women, physical attractiveness did not matter when it came to mating. There were no statistically significant differencee between them in terms of their attractiveness.” 
There is also another study demonstrating that unattractive women are actually more likely to be married by age 30 then even average looking women and with more desirable mates from a betabux perspective:
Kanazawa, Hu & Larere (2018) conducted an analysis of the The National Longitudinal Study of Adolescent Health data consisting of a "sample of 20,745 adolescents" who were personally interviewed in their homes in four 'waves' ranging from 1994-2008. Only the data of those who participated in all waves and didn't drop out of the study was used for the authors analysis.
The authors analysed the data to find how attractive the participants (that were married or cohabitating) had been at the time of the beginning of their marriage or cohabitation, and used income as a proxy for their intelligence (IQ and income being robustly proven by previous research to be correlated.)
The authors concluded that 'very unattractive' women were more likely to be married or cohabitating then merely unattractive or even average to good looking women, and their spouses tended to earn more then their better-looking female counterparts. They infer that intelligent men have a preference to marry or mate with very unattractive women. 
As a result, actual research shows that females tend to be extremely hypocritical when judging men as the gender that’s more superficial.
