As far as living my life, though, I'm totally preference driven and very subjective. Here is a little analogy to help make my position clear:
I strongly dislike the color pink (this is actually true). If I'm around a lot of pink I get irritable and tend to feel claustrophobic.
Let's say for sake of discussion, that numerous studies had been done that proved that pink was, beyond a doubt, the best color and it promoted happiness, stimulated positive brain activity, increased productivity, promoted harmony, enhanced compassion, and on and on and on. And everybody agreed that the studies were well done and the results statistically significant beyond a shadow of a doubt. Perhaps if I bothered to look at these studies, I would also agree that they were accurate.
The first thing to consider is that I probably wouldn't even bother looking at or considering the studies. Because they wouldn't really have anything to do with me. No matter what they said, I still wouldn't like pink. It would still make me feel kinda sick and definitely irritable. So yes, I would simply ignore the data and that would mean I'm essentially ignoring this bit of reality. Why wouldn't I?
So now let's say the government, based on the excellent scientific evidence, decides that painting the country pink is a desirable policy and it has the support of a solid majority of the voters. Pink is now everywhere; there are pink houses and pink buildings and pink cars and pink roads and pink airplanes and so forth. This pink reality has been foisted upon me and I have no choice but to live with it. So what would I do? I would, of course, do my best to ignore it. I would wear blue sunglasses whenever possible, for example. Again, I would do my best to ignore reality.
So now people tell me I'm deluded to ignore reality because reality is getting pinker and better all of the time and everything's really wonderful and thank heavens that scientists were able to prove wrong those charlatans who had the outrageous audacity to claim a few years back that blue was the better color!
At this point, I can only hope to not be sent to the Pinko Archipelago for color behavior reconfiguration.
As most people who know me are aware, I much prefer small, very limited, non-intrusive government. This is a subjective preference and I'm not claiming there's necessarily any objective reason for my preference. I was involved in an email exchange where I think the other person was frustrated that I wouldn't engage him particularly seriously on an empirical level. He had a seemingly unending number of claims (most of them seemed kinda bogus to me) about how wonderful government is (well, at least the democrat portion of it; republicans are, of course, the root of all evil) and how government has made life oh-so-wonderful for everybody, including me.
But just like the pink story above, you could prove to me beyond a shadow of a doubt that big governments were the best thing ever, and at best, my response would be, "yeah, okay, whatever," because it doesn't really apply to me. I'm still not going to like a big, intrusive government and I still am not going to be particularly happy living under one. My solution is to just ignore it the best I can and hope that it doesn't step on me too hard. In other words, my solution is to basically ignore reality.
Delusion can be you friend.
