A Bayesian analysis of the world's $p(\gamma,K^+)\Lambda$ data is presented.We adopt a Regge-plus-resonance framework featuring consistent interactions fornucleon resonances up to spin $J = 5/2$. The power of the momentum dependenceof the consistent interaction structure rises with the spin of the resonance.This leads to unphysical structures in the energy dependence of the computedcross sections when the short-distance physics is cut off with standardhadronic form factors. A plausible, spin-dependent modification of the hadronicform factor is proposed which suppresses the unphysical artifacts. Next, weevaluate all possible combinations of 11 candidate resonances. The best modelis selected from the 2048 model variants by calculating the Bayesian evidencevalues against the world's $p(\gamma,K^+)\Lambda$ data. From the proposedselection of 11 resonances, we find that the following nucleon resonances havethe highest probability of contributing to the reaction: $S_{11}(1535)$,$S_{11}(1650)$, $F_{15}(1680)$, $P_{13}(1720)$, $D_{13}(1900)$, $P_{13}(1900)$,$P_{11}(1900)$, and $F_{15}(2000)$.
