:-) Exactly. In fact, JPEG uses some knowledge of the human nervous system
to throw away information during compression so that the subjective change
is minimized (we are more sensitive to changes in brightness than in hue,
so the YIQ color model uses more bits for the illumination channel than
the other channels, and since noise is mostly of high-frequency those
components are thrown away first in the lowpass step).

Actually, people *believe* they recall events much more clearly, but they
do not recall them more accurately (Pettinati 1988; Register & Kihlstrom
1987). And it has been shown (Sheehan & Statham 1989) that some of the
'memories' that are recalled are actually created during the hypnotic
period due to inadvertent suggestions or facts implied by the questioners.
