Oh no
That's basically the same as the percentage of people who read news stories when responding to or sharing the headline
This link: https://insights.rkconnect.com/5-roles-of-the-headline-and-w... says "Only 22% only read the headline of an online news story, according to data from the Rueters Institue for the Study of Journalism."
But following the link to that study gets me to https://reutersinstitute.politics.ox.ac.uk/sites/default/fil... which… if it supports that claim, I can't seem to find where :P
