Will an Upworthy headline work for you? I performed a short experiment in November-December 2013 timeframe. It’s fair to say that the experiment didn’t have enough data points to be entirely scientific, and Im sure the fact that the experiment was done in November-December (holiday season) will skew the data in some way.
None the less, you can read the startling conclusion to the study here: http://dinodogan.com/will-upworthy-type-headline-work-for-you-a-startling-conclusion
Note: I used Top 10 Upworthy headlines of 2013 as reported by http://pando.com/2013/11/12/upworthy-closing-in-on-50m-monthly-uniques-lists-11-greatest-hits/
