reward you for what exactly?
I'm fine with people wanting to dress nicely as long as they realize it's total bullshit that people are judged by their clothes, but want to take advantage of it anyway. It's just human hacking.
I do feel a bit bad when dressing nicely, because I worry that I am contributing to the continuation of the practice of judging people by their clothing.
Maybe you "hack" HR policies that reinforce the use of proper grammar by refining your resume. Or hold the door open for somebody who is behind you when you'd rather just be on your way. Society is full of norms and social cues, and I don't think it's deception to control your behavior to align yourself with them. To not do so out of some notion that we should combat human instinct is rather naive.
I think Benjamin Franklin put it best: "Eat to please thyself, but dress to please others."
How, exactly, is it naive to try to overcome illogical biases and ways of being manipulated?
Just because we have evolved heuristics for something doesn't mean those heuristics aren't stupid and irrelevant in some contexts.
If you REALLY enjoy it, that's great. But most of the research on the relationship between stuff/trappings and happiness finds that there isn't really any correlation. You're trained by evolution, society, and marketers to want these things, but (unless you're anomalous), they don't impact your happiness.
Meanwhile, 20% of households spend more than they make, unemployed millennials spend ~$800/month on discretionary spending, and half of american households save no money at all.
If presenting yourself well means driving a luxury car, or having an expensive home, then no, I don't respect these people more than others. There are no such 'rules of society' except for materialistic people.
Inverse snobbery is a very powerful thing too ;) But I'm probably an outlier
Besides, why does it even matter if we enjoy something nice because society tells us it should make us happier? Yes, when I go out I DO want society to notice me and reward me. That's the reality of life- people have more respect for those who present themselves well. If the respect of others is something we value, then it makes sense to do what we can to gain that respect. Pretending that you're somehow above the rules of society is both naive and counterproductive. The bottom line is that if it makes us happier or more successful then it was a good investment.
