On the most basic level it does relate to sources.No it doesn't.
This study has nothing to do with sources.
It has to do with judging headlines.
If you can tell bullshit by headlines you are also likely to spend less time ready dodgy sources.
It just means the very basic bullshit filters work for someone.
I would expect we could cut out about half of the crap posted here if people could tell misinformation by headlines.Which is why this study is so useless here.
"Was this a real headline" isn't the problem here.
Then you can dig further and check sources and verify reports.
Perhaps you'd like to dig through the 4,750 pages of material supporting South Africa's accusation of Israeli genocide submitted today.
Let us know if this passes as trustworthy sources.
