There is a recognised human error called "action slip". If you have ever tried to make a cup of tea by pouring the boiling water into the tea caddy rather than the tea pot or put your keys down in an unusual place so you can't locate them - then you have performed an action slip. If you haven't yet - then most probably you eventually will.
A more serious action slip is moving the flap lever instead of the gear lever.

Usually an alert crew will recognise the error and fix the problem. Sometimes if overwhelmed by other distractions e.g. overspeed warnings, "terrain ahead pull up" etc. then the action slip of moving the gear lever in the wrong direction may (did) go unnoticed. But WTF did the crew of PIA 8303 not GA at 500 feet?
