Search engine manipulation effect

Term

The search engine manipulation effect (SEME) is a term invented by psychologist Robert Epstein in 2015 to describe a hypothesized change in consumer preferences and voting preferences by search engines. Rather than search engine optimization where advocates, websites, and businesses seek to optimize their placement in the search engine's algorithm, SEME focuses on the search engine companies themselves. According to Epstein, search engine companies both massively manipulate consumer and vote sentiment, and furthermore do so to ensure their favored candidates win. Epstein’s research shows that such manipulations can shift the voting preferences of undecided voters by 20 percent or more, and up to 80 percent in some demographics, and can change the outcomes in over 25% of national elections.
