The dominant hand reacts faster due to the fact that there are considerably more co-contractions in your preferred hand as you use your dominant hand for every action that you complete only to be aided by the non-dominant hand. All the actions completed by the dominant hand give it an advantage as it is 'practicing'; therefore making the reaction faster. When the ruler drops, the receptor cells (which are the eyes in this case, seeing the ruler drop) respond to the stimulus (the ruler) and set up an electrical impulse in a sensory neurone. When the impulse reaches the central nervous system, another impulse is set up in the relay neurone the electrical impulse then travels up the motor neurone which passes to an effector organ where it triggers a response in the cells of the effector organ, i.e., the hand. This process occurs at a faster rate in the preferred hand in contrast to the non-preferred hand due to more frequent oscillation movements in the dominant hand.

Do you have to write with both hands to be ambidextrous?
No, be ambidextrous means being able to write with either hand equally well. Some people write with one hand and perform other tasks with the other without being fully ambidextrous.
Why do some people experience suddenly skipping words when writing?
Some people may experience suddenly skipping words when writing due to a phenomenon called "word omission." This can happen when the brain is processing thoughts faster than the hand can write, leading to words being unintentionally skipped or left out.
Why do people use their right hand to shake hands?
Using the right hand to shake hands is a common cultural practice that likely originated in medieval times as a way to show trust and peaceful intentions. Since the majority of people are right-handed, using the right hand for handshakes became the norm.
Does the hand that you write with affect how you write?
Yes, the hand you write with can affect how you write. Left-handed individuals may have a different writing posture and hand movement compared to right-handed individuals, which can influence handwriting style and legibility. Additionally, left-handed writers may smudge ink or pencil marks as they write due to the natural hand movement from left to right.
Why is first-hand evidence more reliable than second-hand evidence?
First-hand evidence is more reliable because it comes directly from the source, making it less prone to errors or bias that can occur with second-hand information. First-hand evidence also allows for a more accurate and complete understanding of the situation or knowledge being conveyed compared to second-hand evidence, which may be subject to misinterpretation or misinformation through repeated transmission.
