Why are you not taught to write with both hands?

Writing with both hands, or ambidexterity, is not typically taught because most people naturally develop a dominant hand for tasks like writing. This dominance is influenced by brain lateralization, where one hemisphere is more involved in fine motor skills. Teaching ambidexterity can be complex and may not provide significant benefits for most individuals, as proficiency in one hand often suffices for effective communication and daily activities. Additionally, focusing on developing both hands equally can lead to confusion and reduced skill in each hand.
