It would seem that there is either some intentionally or accidentally introduced perplexities in apt application of empirical facts, versus existential (personally experiential) "facts" or "truths".
In terms of either structured or semi-formal debate, anecdotal evidence is merited only within the context of personal experience (and rationalization of personalized perspective/opinion).
Let's say that we have one perspective lent...predicated upon the anecdotal consequences of excessive alcoholic beverage consumption; followed by such a given person driving a motor vehicle.
It may be a true and verifiable claim by an anecdotal claimant whom may "factually" assert..."I've been drinking and driving for thirty years, and have never had a vehicular accident." Upon minimal research and aptly subsequent verification, one could support such a (personalized) claim as being factual (and even "true" within the given individual's anecdotal "experience").
But would it be fair, or even reasonable, to conclude that such "factual" anecdotal evidence suggests that drinking and driving poses no enhanced probabilities of accident or death amongst those operating under similar circumstance? Not really, no.
Despite the veritable "assignation" of one individual's anecdotal "testimony" or assertion of "fact" as (presumably/assumably) demonstrably "true", it is not compelling or comprehensive "fact" in consideration of similar outcomes/circumstances predicated upon empirical data sets, or multi-faceted and methodologically controlled environments that factor many divergent "personal" experiences (along with the objective observers) into a much broader perspective of evaluation/analysis. It is factually "true" to say...that drivers that choose to drink, then drive, are statistically "proven" to me more prone to accident/death while driving, then those that do not drink, then drive.
If we were to trust to anecdotal/personalized experience alone as arbiter/determiner of abject (and acceptable) "fact", then there would be no value in drawing a reasoned conclusion from empirical data that strongly suggests a differing (and more substantially merited) "fact".
This basic methodological rationale defines the "why" in both the impotency and unconvincing nature of anecdotal "experience", or existential "fact" as (suggested) compelling/persuasive "truth". Personalized experience is a fine foundation as/in support of personalized opinion, but such experience validates "fact" only within the realm of a said singular perspective.
[Note: If any "believers" were wondering why their personal revelatory "testimonies" had little to no compelling impact upon unbelievers, now you know why. When a Christian says, "Jesus changed my life", all an unbeliever hears is, "I like vanilla ice cream more all other flavors";
Well, that's very nice, but...I don't care, because I don't like ice cream].
Empirical data and evidence is meaningless if there is no premised conclusion or logically derived supposition (that invites further review) of value or merit to propose as "factual" or "true". Conversely, empirical data sets will have no persuasive impact upon those that draw inferences/conclusions upon anecdotal/individualized experiences alone, ie..."I know what I know", or; "I've already determined my own "truth" - there's nothing you can say or present that will change that 'knowledge'". This is why "true believers" are only (or primarily) interested in anecdotal ("factual") claims of self-validation, and tend to ignore/avoid/dismiss empirical evidences that challenge/invalidate their immutable conceptions of "fact".
Anecdotal evidence (experience) is primary in substantiating/validating existential "revelations" of claimed "fact" and/or "truth" ["Another person had a prayer answered similar to my own, therefore...prayer works!"], despite the fact that such validations/verifications are neither testable/falsifiable/repeatable in methodologically controlled scenarios/instances. Religious "faith" depends upon, (even demands) from "faithful" adherents - to provide anecdotal "testimony" (or personalized "experience') as evidentiary "proof" in establishment/support of supposed "objective fact" - to proselytize their personalized "revealed understanding" as to what constitutes an erstwhile'/unequivocal "truth (in fact)"
To revisit and reinforce my prior post in this regard...this is why "discussion" can substantially differ from "debate", and why, most often enough, the presentation/introduction of empirical and objective evidence/data remains either unprovided or unreferenced as more substantiative support of assertions of "fact". Rationalists that predicate their perspectives weighted heavily in favor of existential or anecdotal "evidences", will remain at the forefront of denial/avoidance/nonacceptance of proffered empirical data/evidence that suggest any conclusion as valid or merited that suggests that their own conclusions are questionable at best...and demonstrably inaccurate/false at their worst.
It's so much easier to invoke emotion over fact. It's so much easier to dismiss empirically established fact as "emotionless", and cold or ("soulless"). "Don't tell me what your head says! What does your heart tell you?"
If this thread's participants/contributors want to get "deep" into the realm of discussion vs. debate, then ponder whether "emotions" are more/less/equal to objective/empirical "facts" in drawing a reasoned conclusion (that is existentially "true").
Even "belief" is a rationalized choice.
To me, it's not "what" you believe that is of interest or concern - however, the "why you believe"...of "what you believe" (as "fact" or "truth")...remains of paramount intrigue. If you claim that homosexuality is an abomination (against God), or that "Abortion is murder!", or that "Online porn and video games have corrupted the youth of today!" (or whatever grist you find validates the existence of the grinding mill), all I (or anyone of skeptical or "unbeliever" status) requests is veritable support of proffered empirical data/evidence in supported of a reasoned conclusion that bears and exceeds any burdens of acceptably reasonable doubt.
