I can remember, during primary training hood work, the sensation of feeling my inner ear screaming I was straight and level. Meanwhile my eyeballs relayed the irrefutable evidence to my brain that my inner ear and the seat of my pants were wrong. The attitude indicator showed a subtle left bank. The directional gyro was drifting inexorably in that direction, the compass agreed with the DG, and I needed a touch of back pressure to keep the 'nose' level with the horizon on my attitude indicator. That made it four against two. I banked the few degrees to the right to level the horizon.
