We all live in self imposed bubbles. Yup, even the most open minded and curious among us.
We have to. There's just too much going on to be aware of it all. So, we place these bubbles around us: protective info shields that filter out the noise.
As with everything, there's good and bad points to it all. If my bubble excludes most of the crazy noise of measurementist fanatics, I will miss the good points they bring up. Of course, the opposite is true.
Or, what if in my bubble excludes the hinterlands of consumer electronics? Surely there's some excellent parallel technologies in home audio that don't specifically apply to our end of the spectrum—but also might spark an idea I never would have had.
How to expand your bubble? The challenge is like going to the gym. An effective workout only really builds muscle if every week you keep upping your game.
Bit by bit, piece by piece, increase (rather than decrease) your efforts, expanding your bubble (I suspect most of us, as we age, do quite the opposite).
The good news is that new information—even if we don't agree with it—has no negative effects. In other words, it's ok to step into the world of others outside your bubble.
If it gets too noisy, you simply turn down the volume.
