Granted this isn't a peer reviewed paper, but still, a blog that gives personality scores for historical people like presidents can't be based on data.
If IQ is important, maybe it's just that intelligent people know how to take personality tests.

(IQ is a fuzzy, poorly-measured "quality" that doesn't have a whole lot of meaning other than some interpretation of taking a particular test.)
What even is intelligence?
I know that IQ is what IQ tests measure, but what is intelligence?
People say my dog is intelligent, but only in response to her displays of obedience to my commands, I've noticed. I silently translate their comment about intelligence to mean "your dog is obedient."
Does an IQ test measure what makes good employees?
Does an IQ test measure what makes good employers?
Does an IQ test measure what makes good entertainers?
Does an IQ test measure what makes good leaders?
Does an IQ test measure what makes good entrepreneurs?
Does an IQ test measure what makes good spouses?
Does an IQ test measure what makes good neighbours?
Does an IQ test measure what makes good friends?
If an IQ test could measure some factor that leads to happiness, I might consider that factor to be "intelligence". But the things that make people happy vary on an individual basis, as well as over time and circumstances, so how could that be encapsulated in one static test for everybody?
to me, intelligence is simply the ability to discern (useful) connections between phenomena, basically being able to accurately inter-/extra-polate from observation through time and space, or alternatively, the ability to predict the future (for relatively finite values of future). it's kinda like the derivative of knowledge, and wit is the derivative of intelligence.
an IQ test measures a very narrow slice of that. it doesn't encompass humor, art, or sports/dance (dynamic/kinetic ability) for instance.
with dogs (or other pets), the intelligent part is their ability to parse your alien communications into desired responses, similar to learning a foreign language without an instructor, an interpreter, or a reference available.
I've found the following a fairly good definition:
Efficient cross-domain optimization
In less coded language: the ability to gain more benefit across many areas of value from the same or fewer resources.
Your use of the term "more benefit" is clever because it avoids definition, and cannot be disproven.
If you'd said "more money" or "more power" or "more calories" or "more resources" the notion of benefit could be directly assessed, although different people would assess each proposition differently, some positively, and others negatively, because the value of "more" of anything is circumstantial and a matter of taste.
Sometimes less is more.
We might assume that IQ translates directly to ability to reason through a problem, but that may not be the case. An 8 lane highway is useless if you're riding a skateboard.
Higher intelligence = fast learner + better at joining seemingly unrelated dots.
Also why ADHD meds, prescribed legally, are rampant on college campuses.
