Why do people step down ladders facing backwards?

  Unlike the steps in a staircase, a ladder has open rungs and is usually set at a steeper angle than a staircase. It is easier to maintain a firm grip on the narrow rungs of the ladder with one’s toes if one faces it. Also, when climbing down the ladder, a person tends to lean towards it to keep balance, which is easier to do if one faces it. On the other hand, the gentle slope of staircases and wide steps allow people to step down facing forward.
