How Google could select the next president

Imagine an election—a close one. You’re undecided. So you type the name of one of the candidates into your search engine of choice. (Actually, let’s not be coy here. In most of the world, one search engine dominates; in Europe and North America, it’s Google.) And Google coughs up, in fractions of a second, articles and facts about that candidate. Great! Now you are an informed voter, right? But a study published this week says that the order of those results, the ranking of positive or negative stories on the screen, can have an enormous influence on the way you vote. And if the election is close enough, the effect could be profound enough to change the outcome.
…
One group saw positive articles about one candidate first; the other saw
positive articles about the other candidate. (A control group saw a
random assortment.) The result: Whichever side people saw the positive
results for, they were more likely to vote for—by more than 48 percent.
The team calls that number the “vote manipulation power,” or VMP. The
effect held—strengthened, even—when the researchers swapped in a single
negative story into the number-four and number-three spots. Apparently
it made the results seem even more neutral and therefore more
trustworthy.
...
In other words: Google’s ranking algorithm for search results could accidentally steal the presidency.
