To what degree are search engines, such as Google, able to influence Internet users’ perceptions? Senior research psychologist Robert Epstein details a series of experiments his team conducted to study the effects of biased search results on people’s opinions and political voting choices. Epstein’s well-explained findings, in turn, reveal the frightening implications of unregulated technology’s capacity to manipulate opinions on a global scale. getAbstract recommends this article to everyone interested in technology and social science trends.
No one knows exactly how Google chooses to rank its search results, but it’s undeniable that most people choose to view the highest-ranked websites displayed for a given search query. That being the case, could search rankings sway an undecided user toward a politician or stance on a controversial issue?
“If Google set about to fix an election, it could identify just those voters who are undecided. Then it could send customized rankings favoring one candidate to just those people.”
In a 2013 experiment, designed to determine the strength of search engines’ influence, researchers divided 102 people from the San Diego, California, area into three groups. Each group used a fake search engine – “Kadoodle” – which displayed rigged results. Researchers instructed participants to perform searches on the 2010 Australian federal election. Group one viewed search results that positively portrayed a certain candidate, group two saw results favoring a different candidate and group three received mixed search results. Study outcomes revealed that ranking search results to “invisibly” portray one candidate in a positive light can shift user views anywhere from 37.1% to 80%. In a 2014 follow-up experiment, the same research team brought Kadoodle to “the largest democratic election in the world” – India’s race for prime minister. It tested 2,150 undecided, registered voters from across India. They were instructed to perform searches on “randomly assigned” candidates: Rahul Gandhi, Arvind Kejriwal, and Narendra Modi. The team expected participants to have a reasonable familiarity with the politicians, and therefore little swaying of opinion. Surprisingly, the shift in user perceptions deviated only slightly from the San Diego experiment: from 20% to 60%. The results of these experiments gave rise to a new term: the “Search Engine Manipulation Effect,…one of the largest behavioral effects ever discovered.”
“The technology has made possible undetectable and untraceable manipulations of entire populations that are beyond the scope of existing regulations and laws.”
A combination of lack of competition and an abundance of trust give Google vast amounts of power. Some evidence suggests that Google’s results favor its financial interests, but given that search ranking is an unregulated field, there’s no way to demand that Google “go public” about its biases. In theory, any tech company could use what it knows about its users to rig an election – or worse. If tech companies are allowed to proceed unchecked, their technology makes it possible for an “unseen dictatorship” to rise, using the very rules and tools of “democratic government.”
It's been proven that “being yourself” has all sorts of benefits. Authenticity is known to contribute to both overall well-being and engagement. One study on the benefits of authenticity at work found that 80% of self-reported authentic employees believe authenticity improves the workplace.
