I've noticed that after the header redesign
The number of community-pending reviews has gone through the roof.
Personally I dislike the redesign, and I think it's horrible. I'm an old time user and the older header was much better and it was much more appealing to help the community there. (Help with closed votes especially.)
I constantly saw the number of pending reviews and it "hurt" me when that number was too high (for me it was above
1,000) and now it's over
9,000 since the redesign!
I think the psychological effect of the old header was obviously noticeable and it saddens me there were no A/B tests which would have predicted this by measuring how many people clicked the "review" button.
It's clearly as psychological design error.
