Translating the confusing science speak, basically:
Appearance self-esteem takes a hit when they don't fit in a size. They take it out on the clothes: "I hate their stuff, they suck." They buy more of other stuff to compensate for the hit, whether non-sized accessories (I am pretty) or book/tech (I am smart even if I don't fit).
People confident in their appearance are immune to the effect, and simply think it's sized wrong or runs small.
They use precise but indirect terminology e.g., "heightened level of appearance self-esteem" rather than "confident in their appearance".
Indirect phrasing e.g., "they respond more favorably to products that can help to repair their damaged appearance self-esteem" rather than something direct and easy to understand like "they feel bad that they don't fit, so they end up buying other things like makeup/jewelry to feel better about their appearance".
Being able to easily, and quickly read scientific literature is not a universal trait. You're in the top 1% (probably top 0.1%?) if you're able to do that and actually understand the source material.
The average person has a hard time reading and fully understanding a newspaper article or cooking instructions on a pre-prepared meal.
The first paragraph is fine -- I agree. The second paragraph is a silly hyperbole that comes up over and over again on HN and needs to die. Major newspapers are written for about 8th grade level reading comprehension. Cooking instructions on a prep'd meal are probably much lower -- maybe 5th grade. The "average person" (whatever that term means) living in highly developed nations can read at 8th grade level or above.
Why can't you write that? It is much more accurate than their own version since what they wrote is very suggestive while this is just describing what happened.
I think they read the full paper rather than the snippets and agree most couldn't tell you what Cronbach's alpha is, how ANOVA works, or otherwise accurately interpret the meaning of the results sections in a casual read through. One can grab the full paper on resources such as Anna's Archive if they don't have access via a university or such.
Of course, the trick (once you know) is you don't need a comment summarizing it for you. The abstract is alright in a pinch, but the "General Discussion" in psychology papers is the equivalent of "Conclusion" and aims to discuss the results directly. It's still a bit verbose... but the language should at least be very familiar in comparison.
