Data is Beautiful

That doesn't seem like it would be that big an effect. But, perhaps. I know that there have been recent studies about devices used for teaching being poorer. Perhaps that's the problem all round.

I've also seen studies that show our knowledge is now different too. Previously we might remember how to figure something out. Or recall things like phone numbers. Now we recall where that data is available or where we found it. I think there was more available things recalled in the past but more locations now.
