So we have games that measure verbal ability, your attention, your flexibility, so how quickly you can shift from one cognitive task to another, your memory, so this is your very short-term working memory, your math ability, your speed, so speed of processing, and then also problem-solving.

The headline result is that there is a cognitive impact for the working age population.

We're actually finding that the largest effects are for people under 50.

So this is an issue for the working age population, and we expect that to have pretty significant productivity impacts.

The second main result that I think is entirely novel is that it does seem to affect memory ability.

And so if we think across occupations, if we think about sectors that rely more on memory ability, we expect to see the productivity impacts in those areas be more significant.

The impact of this exposure to pollution would be to shift someone in that ranking by about six points.
