An article from the Sydney Morning Herald: Fact: Calling out political furphies works, in Australia at least (with some local flavour)

An article from New Scientist: Australians care if politicians tell lies, but people in the US don’t (from a non-Australian point of view)

The study itself in Royal Society Open Science: Does truth matter to voters? The effects of correcting political misinformation in an Australian sample.

Now that the ballots for the 2018 House of representatives election have been counted, how badly was the vote gerrymandered?

Gerrymandering is the creating of political districts to maximize the number of representatives a political grouping gets per vote.

The degree of gerrymandering can be approximated by calculating the difference between the outcome of a proportional voting system and the actual districted representatives each party gains.

Here's a look at the last 5 elections to the House of representatives.

In this congress, the Democrats have 235 representatives, the Republicans have 199 and there's 1 other representative.

Voter turnout was 50,3%, the highest for a midterm election since 1914.

The Democrats got 53,5% of the popular vote and 54,0% of the seats. The Republicans got 44,8% of the vote and 46,0% of the seats. Others got 1,8% of the vote and a single seat.

Since the Republicans are no longer getting vastly outsized representation, is gerrymandering dead?

If the US would have had a proportional voting system, 7 of the 435 seats would have been distributed differently in 2018.

The Democrats would have had 3 fewer representatives, the Republicans would have had 4 fewer and others would have had those 7 seats.

Here are the similar figures for the last five elections.

The change from getting 27 seats "wrong" in 2016 to 7 seats "wrong" this year is large and changes the historic trend.

Turns out that higher turnout led to more accurate representation in 2018. Who would have guessed.

(There are many other additional possible explanations for why this has changed too)

If we just look at the two major parties, what does this mean in real terms?

Here's an overview of the average difference in the number of voters the Democrats have needed for each seat they actually got in the last five elections compared to the Republicans.

There are other ways of trying to engineer specific election results.

This basic overview only looks at people who actually vote. Therefore it obviously doesn't consider those who are prevented from voting in the election process, whether that's from voting requirements, accessibility of polling places, registration requirements, etc.

It will be interesting to see what happens in 2020.

Is this a trend that'll continue?

Is it just a blip because those gerrymandering haven't been able to predict what party voters vote for in today's political climate?

What about turnout?
