Honestly I think a big part of people looking at headlines and pictures is closely related to people's attention span. Why read many words when less is better. Those same people can't hold conversations for more than a minute or two on the subject then it spirals into speculations which is where the misinformation starts to take place. Society is bombarded with so much information hour by hour people don't want to miss anything so they skim through an immense amount of partial information. It's wild and I'm guilty of it myself so I'm in no place to speak ill of anyone.
