(In paragraph 1 of the executive summary): “Based on human reports of alterations in the subjective experience of time ….I estimate there is a ~70% chance that there exist morally relevant differences in the subjective experience of time across species.”
Could you expand on what these ‘human reports’ are? Is this just referring to anecdotal human reports of time sometimes appearing to go faster or slower?
Yes, the reference is to people reporting that time appears to slow down during life-threatening events, such as fighter pilots ejecting from their jets and rock climbers suffering serious falls. People on certain psychedelic drugs also sometimes report that time seems to stretch out. I discuss these reports in more detail in this section.
