Via @[1702318862:2048:Jason Brennan]. A fascinating study. The authors estimate how Brazilian election results would change if the average voter were as informed as the most informed voters. (Note, original is in Portuguese; this is a Google translation.)
"...we estimate the impact of political information on Brazilian attitudes and electoral behavior. The results suggest that if the Brazilian electorate were more informed about political issues, some of their opinions would undergo substantial changes, increasing support for reducing the state's presence in the economy in certain issues, although also supporting a greater presence of the state in others. Other attitudes towards democracy in general would also be modified. In addition, with regard to voting in presidential elections, data show that, in the 2010 and 2014 elections, the Brazilian Social Democracy Party (PSDB) would be the main beneficiary of higher levels of political information among voters."
