The most interesting thing about the graphs isn't the slope, but that "perceived score" is far more tightly coupled to the individual's perception of their overall ability than their actual score. But that could be an artefact of how and when questions about ability were asked (conjecture: I haven't read the original paper)

"Perception of their overall ability" seems to have a different scale that the 2 others, so the important point is not the actual values but the correlation measure.

Opinion: a log like decrease in happiness vs income is basically consistent with "more money doesn't make you happier". Sketching a graph that is completely flat is misleading however. The only question is, at what point on the log scale is the increase small enough to disregard (compared to other life factors).

Another one from the article: I'm arguing without empirical evidence of the superiority of good type systems (Note: I try to stay away from claims about what those are). I also think it's not possible to make controlled studies on this area - which is why it's such a contested issue. Studies use either students and/or toy problems, or irrelevant datasets such as bugs reported against github repos etc. The only way top make a valid study is to have N teams implement and maintain a product with the same spec over K years and then compare the results and try to factor out developer skill. I say it's not a feasible problem to solve. We'll have to stick to arguing type systems without evidence to back up the argumebts. But that is the best kind of arguing, after all.

Looks like the difference between perceived and actual scores fit the popular understanding.

The people who perform the worst have the most inflated perception of their performance, while the people who perform the best underestimate their performance.

I think people take Dunning-Kruger and apply it to their everyday anecdotes. They are thinking in terms of relative differences rather than absolute, and thus the pop-sci understanding may not be that far off from the original.

Seems paradoxical that the Dunning-Kruger effect is being applied to the Dunning-Kruger effect.

This was my first thought.

I'm sure the noble prize awarded to the Dunning and Kruger's work in psychology was just a result of a bunch of imbeciles who didn't realize it was a "bogus meme".

This article was absolute drivel.

I think you mean log-like increase.

Assuming so, then more money does make you happier (although at a decreasing rate per dollar per year.)

The GP is saying it may be negligible at a certain point, compared to any other conceivable factor.

I just did some quick googling. It seems they received the Ig-Nobel award, not an actual Nobel prize. This award is a bit strange, I don't fully understand... It's some kind of parody:

Sorry yes of course. Log increase. Was thinking the first derivative (rate the happness increases with wealth is negative).

The money/happyness one is particularly interesting to me. If money does not equal happyness why am I so happy when I get more? I make more than 75k so obviously 75k isn't enough.

The fact that you want more is irrelevant. You may be unhappy and believe that more money will make you happier, but it could be just a false belief or a bias.

But the question presumes that somehow you are unhappy because you don't have enough money. What if you are already happy but more money makes you more happy?

Money is not a cure for unhappiness seems like a more accurate phrase.

It's simply there to highlight the wide and wooly range of things being practiced under the umbrella of science. I find it pretty heartening - the world needs research on slug poop and the psychology of sexbots, too.
