Visual Confirmation Bias


Nice term, Paul. Very impressive. Very scientific.

And original. Well, at least I’ve never seen it before so I’m going to claim it as my own.

Visual Confirmation Bias (VCB) is a variation on confirmation bias that postulates that your brain causes audio gear, particularly speakers, to sound the way they look.

I came up with this idea a week ago when I got my new (used) KEF LS50s. (Note: I’m sure that dozens of people have been talking about VCB for a hundred years. I’m not particularly interested in who preceded me but raising points like that is one of the reasons that this forum exists.)


I had read lots about the speaker and I was expecting accuracy and soundstage precision. Their rich, full sound surprised me. These were not adjectives that were usually attached to these speakers.

I’ve been obsessed with these speakers for the past week, reading about them constantly. I find myself most in agreement with The Absolute Sound, which described the speakers—just after they were released—as possessing a “prevailing sweetness, a harmonic saturation that lends it a dark, velvety overall character, and a bloom that is so pleasing that I began affectionately dubbing it the butterscotch sundae of small monitors.”


But in the years that followed, listener after listener reported a “hard” “bright” sound. And when I look at the speaker, those words make complete sense. A tiny metallic driver in a small box? They look tinny and bright so no wonder some people hear that.

My own strongest experience with VCB: Many years ago, on the pretense of looking for a CD player, I walked into Sound By Singer at its old 16th St. location. After just enough feigned interest, I asked the salesman to listen to something “really pornographic.”

Surprisingly, he was happy to take me into one of the listening rooms. The only specific piece of equipment I remember was a pair of Wilson Speakers. I don’t know which model but they were white and just over six feet tall. Each the size of a restaurant-grade refrigerator. They were somewhere in the neighborhood of $250,000.

Then I settled into the listening chair as the salesman started turning stuff on. Preamp, monoblock, monoblock, God knows what else. I just remember him throwing switch after switch. I have to believe all that gear equaled the price of the speakers.

If ever a system should have disappeared, it was this one. If ever the music should have been revealed to me, it was now. But even with my eyes closed, all I could see—and all I could hear—were these huge speakers looming over me. They could not have been more present in my listening experience.

Visual confirmation bias kept me from enjoying the finest pair of speakers that I’ll probably ever hear. The phenomenon is not to be underestimated.

The forward bright sound of the LS50 is probably from people who have a room that’s had some acoustic treatment and is listening on axis, that speaker tilts upward in the 2.5K to 4K frequencies. For a warmer sound like you’re experiencing I will assume you haven’t bothered with first reflection treatments and perhaps don’t sit right in front of them. Just a guess.
If I could figure out how to reprogram my brain and put the cells currently devoted to “Crocodile Rock” to more useful purposes, I could solve global warming. Do you suppose that’s Elon Musk’s trick?
Imagine if you could harness the power of 'Seasons in the Sun'.
Uhuhuhuh, I shudder at such thoughts......
"...Anyone want to comment specifically on the LS50 and it’s supposed forward/bright sound?..."

My LS50s are not bright. I have even tried them with supertweeters. That helped A LOT. I think they sound best with SS amps and maybe some volume to bring the top end up some. With mellow tube amps they are pretty flat sounding (meaning no jump factor).   
kenjit's working right now on his loudspeaker cloaking device (LCD), which will soon become standard on all speakers.
Seasons In The Sun! Now THAT’S music! By? No googling. 

Djones, you’re right on both counts. Believe me, there’s nothing I’d love more than an Eames easy chair planted right at the point of the triangle. But this apartment dictates that the couch go here, the table go there . . .

The apartment is functional, however, in the amusement it provides out-of-towners. “You pay HOW MUCH for rent? I have six bedrooms and a pool and a BMW for the same price!” Us New Yorkers love that conversation. Every time we have it. 

John Updike wrote that New Yorkers share a belief that anyone living somewhere else is, on some level, kidding themselves. Count me among the believers. 

Terry Jacks! I’m not familiar with his ouvre but I’m sure he never again reached such a height.
