About

Videos that give you a new perspective. Here you'll find videos that range all the way from bite-sized snacks to a multi-hour deep dives into the strangest rabbit holes you never even knew you cared about.

Rules

1. Content of posts

All top-level posts should be a link to a video essay that isn't hosted behind a paywall. Any topic is welcome, provided it doesn't break one of the other rules. What's a video essay? See below.

2. Title format

Each post title should include the title of the video, its creator, and its duration in the format [MM:SS] or [HH:MM:SS].

3. Be nice

Be respectful and constructive. No harassment. No grossly offensive images. No hate including expressions of racism, misogyny, transphobia, ableism, xenophobia, homophobia, etc. (although videos where these topics are merely being analyzed are okay).

4. No shitposts

Noticeably low-quality content and videos that stretch any reasonable definition of "video essay" will be removed. If you're not trying to break this rule, you probably aren't.

5. No spam

Don't post the same video multiple times in a short time frame. Don't flood the community with many videos from a single creator at once.

"Video essay"?

"Video essay" is loose genre classification for a type of video that makes an argument or critique, or explains a point of view, usually from a single creator's perspective. They can be short or long, casual or formal, modest or theatrical, and cover any topic.

Video essays are slightly different from documentaries, media reviews, and video journalism, but the lines are blurry, and videos that aren't neatly classifiable are still welcome.

From the video description:

Next video: Simulating the Evolution of Sacrificing for Family - YouTube

TL;DW written with claude.ai from video transcription:

The video explores the evolution of altruistic behavior using computer simulations. It introduces the concept of "green beard altruism" - where organisms with a specific phenotype (e.g. a green beard) help others with the same phenotype. The simulations test whether genes for altruism can spread in a population.

Initially, a simple altruism gene goes extinct, even when the risk to altruists is made very low. Then a "green beard gene" is added, so altruists only help others with the same gene. This allows altruism to spread when the risk is moderate, but it goes extinct at higher risks. Finally, the "green beard" and altruism behaviors are split into two separate genes. This causes altruism to go extinct rapidly, showing green beard altruism is very fragile.

The video concludes that these simulations don't fully explain human altruism. The next video will cover "kin selection" based on Hamilton's rule, which may provide better insights.
