The document discusses the implications of being left-handed, revealing that lefties, who comprise about 12% of the population, may face disadvantages such as lower earnings and higher rates of emotional and learning issues compared to right-handed individuals. Research by economist Joshua Goodman indicates that left-handed individuals are more likely to score lower on tests and have less educational attainment, suggesting that left-handedness is generally a disadvantage. However, lefties born to left-handed mothers tend to have outcomes similar to right-handed individuals, hinting that early maternal influences may mitigate some negative effects.
