The local structure of high pressure BaTiO$_3$ has been interrogated byneutron total scattering methods, up to pressures of 4.18 GPa at ambienttemperature. Competitive refinements of cubic, tetragonal and rhombohedraldistortion modes against pair distribution functions indicate contrasting localstructure behaviour of temperature- and pressure-induced cubic BaTiO$_3$.Suppression of the mode amplitude, isotropy of the order parameter directionand loss of sensitivity to correlated Ti displacements at high pressure allsuggest a high-pressure local structure that is more consistent with theharmonic approximation, rather than an order-disorder model which betterdescribes high-temperature cubic BaTiO$_3$ in the vicinity of the tetragonalphase transition.
