IQ only measures how good you are at taking IQ tests. They recalibrate score every year to maintain the same distribution of scores within a year. (they change what each question is worth so every year 50% of tests get above 100, 40% of tests are between 85 and 100, 40% of tests are between 100 and 115, etc.)
The impact is that they have to make the tests harder every year. If you applied modern standards to 1920, the average score would be ~70.
What makes more sense to you, that 8/10 people today would be considered near-geniuses 100 years ago, or we got much better at taking IQ tests?
It takes some effort to start a fire. Most oils flash points are >600 F, which you might get a pan to to sear a steak, but to heat a pan of oil for deepfrying or something to >600 F, which would be a dangerous situation, requires you to continue heating it after it started billowing smoke between ~350F and ~525.
In any case, if you manage to have an oil fire, say by spilling some on the burner, just let it burn out if it’s a small amount or turn off the heat and throw a towel over it if it’s like a cup’s worth.
Minor burns aren’t uncommon when you’re learning, but that’s just a very quick way to learn “wrap the handle of the cast iron you just took out of the oven with a towel so you don’t grab it like a moron” or “use tongs to place things on hot oil so it doesn’t splatter on your hand”
