Primes¶
- Emotional Contagion
- Online & networked systems: Affective tone propagating through social feeds and messaging networks, where exposure to others' emotional expression shifts one's own expressed and felt affect at scale, demonstrated in Kramer, Guillory, and Hancock's (2014) large-scale News Feed experiment.
This sourceLarge-scale News Feed A/B experiment (N≈689,003) showing affect transfer at scale — supports the marker-369 online/networked-systems claim.

A 689,003-user Facebook News Feed experiment showed reduced feed emotion shifting users' own posted emotion; messaging networks were outside the experiment.
“When positive expressions were reduced, people produced fewer positive posts and more negative posts; when negative expressions were reduced, the opposite pattern occurred.”

- Variation Strategies
- What also transfers is an ethical caveat: variation strategies that affect humans — A/B tests on users, randomized policy pilots, classroom experiments — raise questions of consent, fair allocation of the worse arm, and reliability of measurement, which technical practitioners often underweight when porting tools from non-human domains, a tension Kramer, Guillory, and Hancock (2014) made unavoidably visible with their large-scale Facebook emotional-contagion experiment and the consent controversy it generated.
This sourceLarge-scale Facebook A/B experiment whose subsequent ethical controversy made consent, fairness, and measurement reliability concrete operational issues for variation strategies applied to human subjects.

Confirms a massive Facebook experiment on 689,003 users and shows the authors' own consent justification, but contains no discussion of the ethical controversy, fair allocation or measurement reliability.
“The experiment manipulated the extent to which people ( N = 689,003) were exposed to emotional expressions in their News Feed.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 2 of 2 citations: 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
