Blind Group Buy

Selling something but not saying what it is and implying it might be worth the price. A way to sell something for more than it’s worth. A good of example would be doing a blind buy for a song that nobody really wants for $5k, when the most you would get for that song if it wasn't blind is $2k.

Why would people fall for this?
1. A drought of music and they'll settle for anything
2. Gambling "what if it's the song I want"
3. Retardation

"Oh boy I hope they're selling the song I want in this Blind Group Buy, I'll donate $100 and keep my fingers crossed."

Lie groups

(I'm sorry, they're not groups that Lie) groups of Lie type are the funniest jokes in mathematical group theory. Basically, all the math experts panic because they don't know what to call Liars. They concern "acting on" stuff that is "smooth" and have "many symmetries". (e.g. a piece of paper is smooth but with few symmetries; a circle is smooth (no sudden jolts) and has infinite symmetries.) technically, manifolds

Disputes regarding Lie groups' classification (techincally finite groups of Lie type iirc) happen due to isomorphisms and very similar properties. Derived from the classification of finite simple groups, Lie groups can exhibit unexpected isomorphisms with other types of groups. So we have no clue how to classify them.

Joke: 'Basically, the Lie groups all Lied and so the mathematicians got very confused'

Logical Groupthinking

Similar to Logthinking, but focused on the social enforcement of logical formalism as the only permitted mode of discourse within a group. The group develops a shared dialect of syllogisms and fallacies, using it as a cudgel to win arguments rather than a tool to find truth. Appeals to experience, values, or practicality are ruled "illogical" and out of bounds, creating a sterile, hyper-rationalized echo chamber that is often logically sound but humanly obtuse.

Example: In a philosophy debate club, a member argues for compassion in ethics from a phenomenological perspective. They are swiftly shut down by the club's president: "Your argument commits the appeal to emotion fallacy. Until you can present a formal deontological or utilitarian syllogism, you have no valid point." This Logical Groupthinking privileges form over substance, ensuring only one style of thinking can be heard.

Rational Groupthinking

The illusion of consensus achieved through a process that appears rigorously rational. The group uses shared tools—cost-benefit analyses, decision matrices, weighted voting—but the inputs (assumptions, criteria, data selection) are unconsciously shaped by shared biases. Because the process feels objective, the outcome is unquestioned. This is common in corporate boards, engineering teams, and policy think tanks.

Rational Groupthinking Example: A tech company's board uses a sophisticated scoring system to decide which project to fund. All members agree on the rational criteria (market size, development cost). However, their Rational Groupthink leads them to all weight "market size" based on the same Silicon Valley hype-cycle reports, causing them to unanimously invest in a metaverse project that ultimately flops, while ignoring a less-hyped but solid AI tool.

Room Groupthinking

The phenomenon where the immediate, unspoken social pressure within a specific gathering—a meeting, a party, a classroom—forces individuals to conform their expressed opinions and suppress dissent in order to maintain the group's perceived harmony and momentum. Unlike ideological groupthink, Room Groupthinking is not about a shared worldview, but about real-time social calibration. It’s “Read the Room” weaponized: individuals scan for micro-cues (the boss’s frown, the popular kid’s smirk, the facilitator’s leading question) and instinctively mold their contributions to fit the emerging, often unspoken, consensus of that particular space and moment. The result is decisions and conversations that reflect the room's social physics more than the participants' actual beliefs or the best available ideas.

Example: In a company brainstorming session, the first two suggestions are met with the VP's subtle eye-roll. Instantly, Room Groupthinking sets in. Subsequent speakers, having "read the room," only offer safer, incremental ideas that align with the VP's known preferences. The most innovative but risky idea in the room dies in the throat of its thinker, who feels the social cost of breaking the newly established vibe. The meeting ends with unanimous, shallow agreement on a mediocre plan—a perfect artifact of the room's social pressure, not the team's collective intelligence.

Friend group

A friend group is something so incredibly special. It's a group of people who all are best friends. Not just 2 people being best friends, it's a whole group of people that share the same amazing bond with eachother.

Person 1: should we call the Friend group?
Person 2: like always
