Most people are right-handed but left-eyed. Unexpected results of the study

Scientists have proven that about 90% of the world's inhabitants are right-handed, meaning that they have a better developed right side of the body. However, recent studies show that regardless of whether you are "left, right, or bilateral," we perceive reality better through the left field of vision.

That is, a significant majority of the population recognizes personalities and emotions faster and more accurately when they are in the left field of vision than in the right. Even in animals, one eye sees the target than the other, Sciencealert writes.

Studies show that animals with more targeted vision tend to perform better on survival-related tasks in laboratory experiments. This translates into better survival rates in the wild.

But, of course, the animals that have the greatest advantage are those that look at the ground with one eye (to find food) and the sky with the other (to prevent threats). This "split-brain" advantage in the animal kingdom is important for multitasking.

Each person should have a 50-50 chance of being leaning left or right. However, throughout the animal kingdom, most individuals of a species are oriented in one direction. This suggests that aligning your biases with others in your group may have a social advantage. For example, animals that align with the population during cooperative behavior (shoals, packs) reduce the chance of being picked off by a predator. And those few who turn away from the pack become obvious targets.

Scientists from the universities of Sussex, Oxford, Westminster, London (City, Birkbeck), and Kent tested human behavioral biases. They investigated the connection between the strength of hand bias and performance. More than 1600 people of different ages and ethnicities took part in the study.

The researchers emphasize that people do not always use their preferred hand: some people have a light, moderate, or strong hand.

Also, not everyone knows if they have a visual field shift. Therefore, the scientists evaluated the facial expressions of the participants.

Interestingly, people with a mild to moderate hand bias placed more colors correctly than people with a strong or weak bias. These results suggest that in humans, extremes can limit our performance flexibility, unlike in wild animals.

The vast majority of study participants also had a standard bias, i.e., right-handedness for motor tasks and a left visual field bias for face processing.

Scientists have emphasized that humans share most of their evolutionary history with animals. Therefore, people need to study themselves in the context of the wider animal world if we want to truly understand our modern brain and behavior.
