(WVUE) - A new study suggests you can determine how men treat women by looking at their hands.
Researchers at McGill University in Canada did a study on finger size ratios in males. The study found guys whose index and ring fingers are similar in length were more likely to smile and laugh, compromise or compliment women.
Researchers say if those fingers were different in length, the men were more likely to be quarrelsome, stubborn and rude.
Researchers say for women, the ratio variation did not seem to predict how they behaved.
The study was published in the journal Personality and Individual Differences.
