Nobody here is disputing that you can get information about subjective experience by asking people to describe their subjective experience
...if that is your conclusion then you simply have not been reading the posts. I can grab a pile of quotes that flatly claim that anecdotes (descriptions of subjective experiences) are evidence of absolutely nothing!
Nobody here seems to want to accept the blindingly simple fact that anecdotes (aka: what you call a description of a subjective experience) describe subjective experiences.
…but we’ll keep things real simple so that everyone can follow along.
Question #1: When someone describes their subjective experience…does that qualify as an anecdote, a personal account, a self-report?
Question #2: Does it really matter what specific word you use to describe what you call “ a description of a subjective experience”….? That is the meaning…so that is what we are talking about. Someone communicates / describes their thoughts, feelings, experiences on anything under the sun (your post qualifies as just such a thing).
…is that communication / description evidence of those thoughts / feelings?
You have just answered a resounding ‘yes’ to that question. If someone is describing their thoughts / feelings / experiences…then that description is evidence of those thoughts / feelings / experiences.
Thus…by default and definition…this description / anecdote / whatever-the-hell-you-want-to-call-it has evidential qualities (which is precisely what a great many of the posts on this thread refuse to acknowledge).
Is the statement: “I just ate some cheese.”…evidence that I just ate some cheese?
Is the statement: “I feel sick.” …evidence that I feel sick?
Is the statement: “I love my wife.”…evidence that I love my wife?
Is the statement: “I disagree with you.” …evidence that I disagree with you?
Is the statement: “My computer does not work.”…evidence that my computer does not work?
Is the statement: “I understand particle physics.” …evidence that I understand particle physics?
Is the statement: “I despise Trump.”…evidence that I despise Trump?
Is the statement: “I have a million dollars in my bank.”…evidence that I have a million dollars in my bank?
Is the statement: “I just experienced an NDE.”…evidence that I just experienced an NDE?
Only a complete idiot would insist that ‘no’ is the answer to the first eight questions…so why is the ninth question suddenly different????
...and if you're still convinced that anecdotes have no evidentiary legitimacy...then take your ass down to your nearest law court and discover what is happening when someone is sitting in the witness box and describing their thoughts / feelings / experiences. The entire judicial system would collapse this moment if anecdotal evidence had no relevance...
...and we even have one of you who claims to be a practicing lawyer who has argued in support of this nonsense!
