The Power of Assumptions


A few weeks ago I was in some leadership classes at work that were taught by an PhD Industrial Psychologist. It was very interesting and I learned a lot. He was very knowledgeable about what is going on inside the brain during different actions and thought processes. One example was that the act of throwing a ball to someone on the move (i.e. playing catch) uses the same pathways in your brain that all delayed gratification decisions do. You are holding the ball while visualizing where the ball and person will meet at a point in the future. This is why it is very important to play arch with your kids. It trains their brains to use these pathways and help them develop the skills necessary to delay gratification.

How does this relate to audio? Another thing he takes about was the power of assumptions. When we believe/assume that something is true the way our brain reacts to it chemically and electrically is identical rather it is in fact true or not. The secondary effect that happens is that we then become supremely aware of every little thing that supports our assumption and we blindly ignor anything contradictory. He said that this is why it is so difficult to get someone to change their opinion of you. His point was that we needed to be aware of this involuntary response and be willing to ask ourselves if there was any other way to look at a given situation.

It made me think about how this directly relates to audio. What we assume can actually have a stronger impact our experience than the objective facts. For example, if I assume that solid state amplifiers are inferior it will be extremely difficult for me to have a positive experience with one because my brain will be working overtime to find a way to support my assumption. It might take hearing a solid state amplifier while believing it to be a tube amplifier to force my to be objective and at least consider that a solid state amplifier might sound great.

How many times have rooms at audio shows been the focus of blame when the reviews touted otherwise?

It's now conventional wisdom to blame the room but I seriously doubt that most of the rooms that fared poorly at audio shows had otherwise great equipment in them. We all want to believe things despite evidence to the contrary.

Granted, one piece of equipment can make or break the chain as I've heard the best digital ever from MSB a few years ago to only wonder what the hell happened the year after. It was partnered with different speakers.

Great gear combined with great gear will usually guarantee great results but one component can't do it on it's own despite the rave reviews. That highly touted component thus becomes the placebo. Quite the turn of events, eh?

All the best,

Placebo doesn't eliminate the possibility of objective factual opinions. I don't think it is as much a factor on equipment like speakers and amplifiers where the differences can be significant, but for things like cables, isolation devices, etc., where the differences are often small the impact can easily become more real.
If a placebo improved the sound of your system noticeably would you pay say $100 for it?

Geoff, you probably have the best market research on this subject :-)

Good Listening

Cannabinoids improve my critical listening(maybe that's placebo), but sometimes I do spend $100 or more dependint on my supply status:-)
