Dumb intonation question

[hublocker]

When a string is in tune with the tuner, but is shown as sharp when fretted at the 12th fret, do I move the moveable bridge for that string towards the headstock or towards the tail peg?

[fourstringdrums]

Toward the bridge, thus making the string longer.

[scottbass]

"tail peg"? You must have started on upright bass, eh?

[andysick]

Sharp move to bridge.
Flat move to nut.

I remember it by associating "flat nuts". Weird, but works for me.
