Google’s Experiments to Mess With Your Mind

Here’s an A/B experiment that Google has conducted. See if you can spot the difference.

Page 2:

Yeah, I didn’t spot it either, but apparently there is slightly more white space around the first listing, in page 1.

Should you be that granular with your A/B testing? Maybe not, but Google explains just how subtly it’s messing with your mind testing your preferences each day.
