Fact from fiction, truth from diction. We as humans are hard wired that way. We are predisposed to having things symmetrically balanced and pleasing. That goes to everything, not just what a person appeared like. If you were at a restaurant and you and 3 other friends had your food comes to the table if you and another friend ordered the same dish but yours cam with the peas is slopped in to the mashed potatoes which is also slopped partly over the entrée you’d more than likely complain about how the plate was made. In the end once you started eating it, the appearance of the plate is moot. The appearance of the food means nothing the once you start eating it and once it is in your body, it all gets mixed together. It just looks more appetizing when it is arrange on the place nicely.
If you were on a business trip and you were in two groups and had to take rented cars to wherever, if you had the choice of a newer shinier car or an older less glamorous model most would gravitate 1st to the newer model, even if it didn’t have as good A/C or the radio didn’t pick up as well as the older model. Shinier and newer equals better.
No difference when it comes to humans, a guy dressed sharply in a 3 piece suit will be seen more educated or successful than a guy in cargo shorts and a over-sized jersey top. A woman like this will dozens of times be seen as more attractive than this. When people meet up with strangers at a mixer and BBQ few are thinking “that geeky guy over their looks like he has a very interesting personality and riveting conversation”, or that plain Jane that she has a great bubbly attitude and laugh, people are sizing up who they can see themselves long-term with or at leas the next few months which these days means sex is the ultimate goal. So if the person is not pleasing to the eye it is hard to be pleading to the loins.
Want to test it out? Here is a test, next time you have a function where there will be young people there bakes some small pies but make one slightly bigger and flakier than the others but only put half the filling and make the filling not near as sweet. Just off how it looks I bet most will angle to get it, even though they have no ideal how it will ultimately taste. If it looks the best it has to be the best. Same with humans…..just the way we are wired. It is our own individual gumption that can override that.
