Psychedelics permanently increasing your openness to experience sounds true to me based on my own experiences, however not in the way that the author seems to be fearing. It's not some subtle unconscious change. It's a conscious choice to be more open, in certain ways, based on the new insight gotten from your emotional psychedelic experience. It's a freshened perspective on life. As for the examples of believing in astrology, aliens, doing yoga, or constructing models of consciousness. How weird are these really? To me these seem like viewpoints that regular Joe will discuss in a pub. Some, e.g. modelling consciousness, aren't even irrational, but I've personally found that almost everyone has at least one irrational pet idea anyway. Psychedelics could certainly amplify your own beliefs, but I'm not convinced it can easily create new ones. It can make you more open to the idea of being honest about your thoughts, including sharing your alien theories.
