First-hand experience is great for many things. You’ll get great stories, you’ll meet great people, for starters. Unfortunately, it won’t get you everything.
The problem that arises from people who’ve “been there” is the notion that their experience is absolutely everything. Unfortunately, if you get kidnapped by Doctor Who (and really, who wouldn’t want to be?) and take a journey back in Earth’s time-line, and encounter many people who’d “been there” for several history-making events, you’ll probably get a very different story than what was told in your history books. Sometimes, this is because your history book is little more than a propaganda tool –but other times it’s because the people “who were there” were either intentionally dishonest about the whole story or, simply, they didn’t even know it. Even in 2012 in the Amerikan $outh, the notion permeates that the Amerikan Civil War was “all about $tates’ rights, not slavery” —but as any-one with even a BA in U$ History can tell you, that’s the primary “$tates’ right” that the $outh cared enough to attempt to succeed over and then go to war over at the time.
“Oh, but my great=gret grand-pappy WAS THERE! It had nuttin’ to dew wit’ slaves!”
This is what anecdotal evidence gets us: People confuse feelings and partial information for hard facts. Hard facts, thus, are more eagerly absorbed by people who have little emotional attachment to “being their” either because they simply weren’t and have no loved ones who were, or because they simply have a personality that doesn’t become a slave to nostalgia.
This is where I run into personality conflicts with the odd person on Mod fora: The plural of anecdote is not fact.
Oddly, I run into this more when the conversation drifts outside the realm of the Mod subculture in specific and into the realm of other scenes. Weird, eh? I thought so. When I point out the origins of, say, the punk scene or even the etymology of the word, I’m not telling people that their experiences as youth are wrong; I’m simply saying that they don’t have the whole story. I’m able to see the whole story because, frankly, I lack cognitive biases that experiences can sometimes lead to. Unfortunately, people tend not to acknowledge their own cognitive biases, leading to the notion that experiences are everything (except, of course, when they aren’t) and the fallacy of “anecdata” — id est, “I was there, and so were my friends, and thus it is true”.
It’s great to have experiences, and especially memories of them, but when the ideas brought on by experiences and nostalgia are at odds with actual verifiable facts, then you’re having a problem. Step back and examine things! Think! Learn! Grow! Old dogs can learn new tricks and nostalgia need not be shackles holding you out of range of facts.
