 The psychologist Ralph Hood (2006 and 2017) argues that psychometric studies provide “strong empirical support” for the common core thesis. Does the fact that neuroscientists have found different patterns in the brain for different types of mystical experiences and meditative practices (see Section 9.7) mean that the experiences must be different? Even if there is a common neural basis to all mystical experiences, does it mean that the phenomenology of the experiences must be identical?
