"Even a broken clock is correct twice a day"
Even if bogus ideas get some things right, they'll also lead you to believe incorrect things and make incorrect decisions. If that bogus theory touches on personalities and personal capabilities, it means that you're going to end up hurting people.
In the workplace, it means undeserving people may get rewarded while hard workers are not, or that socially unhealthy people get put into positions of power and authority.
In interpersonal relationships it means you'll be conducting yourself with social rulesets that may confuse people or reflect a set of ethical beliefs that don't align with your personal beliefs. It might also undeservedly color a person more attractively to you who, in the end may be unhealthy for you. And visa-versa.
On the flip side, it'll also act with the same effect as bright flashy colors on plants and animals in the wild; if people who are smart enough to spurn superstition and pseudo-science notice you making odd decisions due to those things, or even just learn that you believe those things, they'll inevitably become more socially aversive with you to avoid dealing with the troublesome issues that arise from it....like awkward conversations where they try to change the topic or quit it altogether while trying to remain polite and not say something hurtful regarding your beliefs.
That being said, maybe the mental health benefits of putting faith in simpler things, in a society that can't afford better mental healthcare to all, is overall better for your long-term health and happiness.
Considering that superstition and pseudo-science is overall bad for society, though, and regularly commits atrocities because too many people allow it to exist without proper regulation, I personally can't approve of it.
