Ok so there’s a conspiracy theory going around that this woman was faking her injury with an onion.

This is likely false. Onions are a folk remedy for pepper spray.

The theory, which has some merit, is that since onions make you cry, it helps flush the irritants from your eyes with natural tears.
However, this is not recommended as a treatment for pepper spray and is ultimately not very effective.
Pepper spray, tear gas, mace, CN, HC, and other agents are best removed with a flush of water or, if you have the proper mixture, saline. Nothing else.
We do not do chemistry in our eyeballs. We are not putting chemicals in our eyes. We are not putting produce in our eyes. We are removing the chemicals with safe, neutral water.

I know you will try to be clever by suggesting milk or LAW or apple cider vinegar but you are wrong
Once again, we are not trying to bind anything, particularly things our patients may be allergic to, to capsaicin molecules we cannot be certain are present in the irritant.
There are at least half a dozen different chemical irritants in common use and unless the cop who sprayed you also gave you the MSDS, you flush with water.

And if they did give you the MSDS, it would tell you to flush with water.
When you are in a chemistry lab, there is no milk flush station. There is no vinegar flush station. They do not keep a supply of fresh onions.

There is a water flush station because what we flush our eyes with is water.

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE


2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less.

3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)


4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3


5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)
