Why do people use two or three fingers instead of one to check a pulse?

More fingers equals more surface areas. It’s easier to feel the pulse across a larger surface area (more finger pads) than a smaller one (just one finger) The signal becomes more distinguished and thus easier to tell.

Going off of first response, sometimes with pressure, you can end up feeling your own pulse when pushing down. Using multiple fingers reduces this issue.

*Including only because people on this site enjoy splitting hairs.. it’s not usually an issue either way because you can very easily feel a pulse with one finger depending on where you are palpating, but this is somewhat of a norm in teaching and given different calloquial reasoning depending on who you ask.
