This is a graph of people who liked a new, “crowdsourced”, design of myyearbook.com compared to the old one. I’ve never even been to their website, and I don’t really care a bit about their new design (besides being interested in the crowdsourcing part), but the consistency of this is pretty amazing.
The independent variable here is age; the site was redesigned the same for everyone. So basically, as you get older, you’re not as receptive to change! Not surprising, really, but something one doesn’t often think about and something that is so beautifully illustrated in this graph.
