Evidence of massive-scale emotional contagion in social networks (2014)
- eiaoa 8y agoThis needs "(2014)" added to the title. This appears to be a repost of the famous Facebook study that manipulated people's news feeds: https://www.theatlantic.com/technology/archive/2014/06/everything-we-know-about-facebooks-secret-mood-manipulation-experiment/373648/ https://www.theatlantic.com/technology/archive/2014/06/every...
- pie_hacker 8y agoI agree. Although perhaps more infamous than famous.
- notJim 8y agoThanks, I thought this was new, and was kind of amazed that they were doing this again.
- kevmo 8y agoOP here, and I agree. I will keep that in mind for next time. :)

- trustmath 8y agoEvidence is better than common sense.
- youwindang00 8y agoYou want evidence that humans are able to be manipulated at scale? https://en.m.wikipedia.org/wiki/Religion https://en.m.wikipedia.org/wiki/Religion https://en.m.wikipedia.org/wiki/Capitalism https://en.m.wikipedia.org/wiki/Capitalism https://en.m.wikipedia.org/wiki/Nationalism https://en.m.wikipedia.org/wiki/Nationalism https://en.m.wikipedia.org/wiki/Advertising https://en.m.wikipedia.org/wiki/Advertising Etc, etc... There’s an interesting parallel here. When an obvious thing is granted a software patent because it’s the first time it was done “on a computer.” Human society has a long history of being gullible and easily manipulated at scale. Facebook is just tapping into that nature “on a computer.”
- StefanKarpinski 8y agoAn important point about this result: the significance is high because they had a huge population to test on, but the effect size is very small. The effect size is 0.001 which means that if one of your friends posts something negative (or positive), you have a 1/1000 chance of also posting something negative (or positive) as a result that you wouldn't otherwise have posted.
- b_tterc_p 8y agoAnyone want to do a power calculation for an effect size of 0.001 and a sample size of 700,000? Eyeballing it, I’m not convinced that’s enough.
