Eye test

[Phlegmak]

1 letter of numeral in each group is different from the others. many people won't spot that right away.

I realize all that, but typically these tests are like "spot the X in under Y seconds. If you can, you are normal. If you can't, you are abbynormal." I suspect I'm just expecting to find purpose where there isn't any.

Not every test is well designed
