Deduction Tip #3

There are many ways to tell if a person is right-handed or left handed. One previously mentioned is wherever you see a callus on the last knuckle of the middle or ring finger, this is where the person rests his/her pencil when writing. Another method I to observe on what side a person keeps his/her phone or wallet, as they will most always be on the dominant side for simpler access. Hand positions can be an even more obvious indicator. When a person crosses his/her arms, the dominant arm will usually be the arm wrapped under the other. When holding his/her hands together either in front or behind him/herself the dominant hand will usually be placed in the less dominant one. These both occur due to the natural instinct to "support" the less dominant hand with the more dominant one. Lastly, when a person claps, they will almost always clap into his/her less dominant hand, i.e the palm of his/her less dominant hand will be more angled toward him/herself than the dominant hand.
