I’ve seen the good, the biased and the BS around this sport, and life in general, for many years now. Thankfully, what I sell is information with an intent to be as unbiased as humanly possible.
We’re all biased to some degree. I prefer paramotors with weight shift and, given my propensity to prance about while wing handling, like them to be well balanced on the ground. But I know about these biases which makes them easier to avoid. Another easily avoided bias is the profit motive—I make no money from selling equipment and even a perceived bias hurts credibility.
The hardest bias is personalities. There are people whose obnoxious behavior makes it hard to recommend anything they’re involved with. That’s not fair, of course, and I try hard to look past it or make it clear why the bias is there. The opposite is true when it may be a good friend who’s selling something that I’m not so fond of. Gotta take the good with the bad if you’re gonna be credible. I’ll try my darndest.
