Dear Software Makers

I strongly believe A/B testing users without their knowledge and enthusiastic consent is unethical. If you don't have enough confidence in your changes to make them carte blanche, then don't make them at all. Users don't want their shit changing all the time.

"There’s this sort of unspoken rule of community on YouTube, that like we’re all having this same experience together — we’re all watching the same video. That is what makes it a cultural phenomenon is that we all saw the same thing […] so letting people put up two or three different videos of the same thing at the same time kind of fundamentally breaks that, which doesn't feel right."

It's going to be awkward if you share a youtube link with somebody and what they see is significantly different from what you saw, perhaps even to the point of them replying, "Why on Earth did you send this to me? Are you on crack?"

More importantly, this will almost inevitably lead to content creators being given the ability to not just randomly A/B test versions of a video, but produce different versions of the same video that are shown to users based on their data.

e.g. Shania Twain used to produce different versions of her albums with different instrumentation based on which section of the music store they'd be sold in. There was a Country version for the Country section and a Rock version for the Rock section. She's still bootin' around today, so she could produce different versions of music videos targeting users based on whether Google thinks they like Rock or Country more. This would be relatively harmless, although one might be surprised by the version that appears on a friend's phone.

Musical taste isn't what really divides people these days. What might content creators do if they could show different videos to people based on their political views? This might be good for their business, but it undermines objective reality. People would be shown different "facts" based on their beliefs. This is precisely the opposite of what needs to happen to reduce political polarization and bring people closer together. A common reality is necessary for society to function.

Could go even further and produce multiple sections and let the "algorithm" edit them together in whatever order.

intro (2x 15 second clips pulled from random places in all the other sections)

section 1 (a/b/c)

section 2 (a/b/c/omit)

section 3 (short/long)

section 4 (a/b/c)

It would be like a choose your own adventure video, without the choosing, or the adventure.

I'm not a fan of the new approach, which is, basically "We don't need to be creative, up front. We'll just shove some crap out quickly, and work on the friction points."

But it's not that simple. We definitely need to "pave the bare spots" (desire paths); It's just that we need to start off, at what we sincerely believe to be an optimal place, knowing that it isn't, in fact, optimal.

> The skill of being a “creator” is not about maximizing views, retention, etc. It’s about finding creative ways to share stories, teach concepts, explore ideas, etc. Views, retention, etc. are all downstream of that.

this seems wildly naive

In most cases the A and the B in an A/B test really should otherwise mostly identical, but one thing is different.

If almost everything is different, it’s hard to learn for next time what exactly what led to a change in which ever dependent variable your observating.

Welcome to a world where commenting on a YouTube video is the same as writing a product review on Amazon. Now you need to include enough details that future readers will be able to tell that you are talking about a different product/video.

I've seen this argument a few times and honestly I don't get it - how do people propose we otherwise measure relative success of particular interventions -- Vibes? I've found that people who complain about how everything needs to be measured and how measurements are imperfect are often just bad at devising measurable quantities as proxies of real-world benefit. Sure it can take a bit of time to devise such measurements, and they're not inherently valuable, but if I can prove that a given variant performs better, why not pursue the preferable alternative?

It seems easy enough to say "keep the youtube we love" but how do you think this variant came about in the first place? I can assure you there have been numerous A/B tests that have led to the current feature set. And even if its a local rather than global maximum, at least there are measurable qualities by which it is preferable. Also - do you believe that everyone who says this is harkening back to the same historical reality? This is quickly approaching "make youtube great again" territory - when exactly was it great again? and why? This statement is easy to agree with and hard to prove.

It also seems easy to handle links to different variants; just supply a URL parameter. This is a non-issue.

If someone out there has a non-tea leaf divination style alternative to measuring things as a way to determine success, I'm all ears, but I don't believe in fortune tellers, and people who make software shouldn't either.
