Bible of BS Case Study

“It’s just common sense.”

A phrase said with condescension, usually when someone doesn’t want to explain themselves—or can’t.

But let’s be honest:

Common sense isn’t common. It varies wildly by culture, upbringing, incentive, age, industry, and lived experience. What’s “obvious” to you might be invisible or absurd to someone else.

That’s why appealing to “common sense” as a correction isn’t instructional—it’s shaming. It doesn’t make people smarter. It just makes them feel small.

And let’s not forget—the world is full of bullshit. Most “simple” things, assuming they can actually be agreed upon get quickly twisted from bureaucracy, laziness, corruption, and self-interest.

So when someone says “it’s common sense,” what they usually mean is:

“I don’t have the tools or patience to explain it better.”

That’s not wisdom. That’s intellectual cowardice or at best lazy ignorance.

Commandments Violated:
2) Thou Shalt Be Ignorant
They assume their own worldview is the default. If you don’t share it, you’re labeled stupid—not curious.
4) Thou Shalt Be Unresourceful
They don’t bother to explain, simplify, or clarify. Instead, they reach for the laziest tool in the drawer: shame disguised as guidance.
6) Thou Shalt Make Improper Assumption
They assume knowledge parity. No room for different upbringings, industries, or perspectives. Just: “you should’ve known.”
7) Thou Shalt Misrepresent
They distort the situation. “Common sense” gets wielded like a universal truth, even when it’s just personal bias with a smug accent.
10) Thou Shalt Have Indecent Regard for Others
Their tone isn’t helpful—it’s dominant. They’re not trying to bring you up. They’re trying to put you down.
