Reviews: A Bayesian method for reducing bias in neural representational similarity analysis

The paper explains well how computing RSA using estimates of regression weights can result in a biased similarity matrix. However, in many cases in neuroscience, the RSA is computed directly on the patterns of activity, and not the estimates of regression weights beta. This diminishes the relevance of this paper to the neuroscience field. The authors very briefly address this alternate way of computing RSA in lines 123-128. It is unclear how this alternative RSA computation is biased if it does not depend on a proxy for beta estimates, and needs to be addressed further.
