Experimental Evidence of Massive-Scale Emotional Contagion Through Social Networks
Research-assisted source review
- What it supports
- Reducing positive content produced slightly fewer positive and more negative words; reducing negative content produced the reverse. The shifts were statistically detectable but very small.
- Where it may not transfer
- Word counts do not directly measure felt emotion or wellbeing. People did not provide study-specific informed consent, the journal issued an expression of concern and vulnerable-user harms were not measured.
