Abstract
Chiral loop corrections for hadronic properties are considered in a constituent quark model. It is emphasized that the correct implementation of such corrections requires a sum over intermediate hadronic states. The leading non-analytic corrections are very important for baryon magnetic moments and explain the failure of the sum rule (μ(Σ<sup>+</sup>) + 2μ(Σ<sup>-</sup>) /μΛ = - 1 predicted by the constituent quark model.
