Dear student,
Carbocation rearrangements are more common than the carbanion or radical counterparts. This observation can be explained on the basis of Huckel's law. A cyclic carbocationic transition state is aromatic and stabilized because it holds 2 electrons. In an anionic transition state on the other hand 4 electrons are present thus antiaromatic and destabilized. A radical transition state is neither stabilized or destabilized.
