Grazie. Veramente strabiliante.

[...] In most countries, 90 per cent of online search is conducted on Google, which gives the company even more power to flip elections than it has in the US and, with internet penetration increasing rapidly worldwide, this power is growing. In our /PNAS/ article, Robertson and I calculated that Google now has the power to flip upwards of /25 per cent of the national elections in the world/ with no one knowing this is occurring. In fact, we estimate that, with or without deliberate planning on the part of company executives, Google’s search rankings have been impacting elections for years, with growing impact each year. And because search rankings are ephemeral, they leave no paper trail, which gives the company complete deniability. [...]

We present evidence from five experiments in two countries
suggesting the power and robustness of the search engine
manipulation effect (SEME). Specifically, we show that (i) bi-
ased search rankings can shift the voting preferences of un-
decided voters by 20% or more, (ii) the shift can be much
higher in some demographic groups, and (iii) such rankings can
be masked so that people show no awareness of the manip-
ulation. Knowing the proportion of undecided voters in a
population who have Internet access, along with the pro-
portion of those voters who can be influenced using SEME,
allows one to calculate the win margin below which SEME
might be able to determine an election outcome.
