VERMONT–The tragedy in Las Vegas has ranked as the saddest day ever on Twitter, according to a university professor.
It’s rated using a program called “Hedonometer” it’s been developed over the last 9 years to gauge people’s well-being around the world.
Hundreds of millions of tweets are sent every day but the program only looks at about 10% of them.
Tweets that contain any number of ten-thousand emotional words like love, or hate, evil, and shooting which are ranked on a happy to sad scale.
There are noticeable trends using the program.
“Some of the things we’ve found is there’s a very regular weekly cycle, said Professor Chris Danforth Computational Story Lab at The University of Vermont. “People tend to be happier on Saturdays and sadder on Tuesdays. And there are deviations to that weekly cycle due to U.S. holidays tend to be happy days on the hedonometer. And then natural disasters and terrorist attacks and things like that tend to be sad days.”
The saddest day before Monday? The day of the Pulse Nightclub shooting in Orlando.
Since 2006 there’s been a downward trend overall.
Still, researchers say there are more positive words on Twitter than negative words.
