Henry:
I totally agree with your assessment of the reason for the shrinkage
of so many of your colleague's brains.
Being an early diagenetic product, they maintain a spherical to
semi-spherical form (frequently compressed by late diagenesis and/or
metamorphism) and often are hollow from replacement or gel-state
shrinkage.
This deplorable condition, most frequently triggered by a steady dose
of brainwashing on a college/university level, is known by
neurologists as Petrified Brainitis.
And, the sad part, they still haven't come up with a cure.
