that there was an objective reality, but that it was constituted by what he called intersubjectivity. This comes about through shared experience, which is made possible for us by our embodied existence alongside other embodied individuals.

if the same effects can not be observed by multiple experimenters, it is no longer consider an objective finding but rather it has been corrupted by the bias of one or both subjectivotoes of the experimenters. This is the challenge encounered in psychodelic research and the key to primary school level science; the capacity to adequately control variables in order that intersubjective awareness of findings can be established.
