We study the Fisher metrics associated to a variety of 
simple systems and derive some general lessons that may have important 
implications for the application of information geometry in 
holography. Some sample systems of interest are the classical 2d Ising 
model and the corresponding 1d free fermion theory, the instantons in 
3+1d massless phi^4 theory, and coherent states of free bosons and 
fermions.
