Good-looking people are more likely to end up right-wing, new research has found.
The authors of the study say it's because attractive people tend to end up paid more, so are less-inclined to support wealth redistribution.
Volunteers in the study were shown photographs of politicians from Australia, Finland and the US, and in all three countries they rated politicians on the right more attractive than those on the left.
"This is bound to have political consequences, as their beauty advantage, all else equal, makes candidates on the right more likely to win office and implement their preferred policies," the study reads.
The authors also noted previous studies have shown good-looking people are "treated better than others, achieve higher status and are happier", so are more likely to see the world as "just place... and embrace conservative values".
"A frequent reason for people to sympathise with the left is a perception of the world as unfair."
Another finding was that in low-information elections - where voters know little about candidates - the right has more success because people are naturally inclined to vote for better-looking people.
"The general appreciation of beauty among voters means that politicians on the right, who look better on average, have an advantage in elections."
Right-leaning voters are also more swayed by a candidate's looks, the study found.
"The average margin of victory of the more beautiful candidate is larger among voters on the right, indicating that they respond more to beauty."
The research was published in the Journal of Public Economics.
A recent poll found Jacinda Ardern - a leftie - was ranked New Zealand's sexiest politician.
