AI could read your handwriting to figure out your nationality

The researchers created a dataset of 100 people from those countries and had them write in English, with 500 lines done in total. With those handwritten lines, a tool called Cloud of Line Distribution, or COLD, breaks down individual letters, measuring the straightness or curviness of the text. The algorithm performed better at determining the nationality of the writer than the current existing method put to the same task, more than doubling the correct predictions for some countries. The algorithm is doing what machine learning does best--picking up on patterns. For example, when native Chinese writers use the Roman alphabet, they end up writing letters with straighter lines since Chinese characters are usually formed with the combination of straight strokes.
