I Don't Like Where This Is Going, So It Can't Be True

How wishful thinking hijacks logic


🔥 Hook

Pop quiz.

If it turns out vaccines cause autism — which they don't, science is extremely clear — but if they did, would that mean doctors lied to us?

If evolution is real, does that mean humans are "just animals" and nothing matters?

If climate change is real, does that mean we'd have to give up cars, meat, and basically everything fun?

Here's what some people actually conclude from those questions:

"I don't like those consequences. Therefore it can't be true."

That's Appeal to Consequences — and it's one of the most widespread logical fails on the internet.


🧠 What's Actually Happening?

The Appeal to Consequences fallacy works like this:

Someone looks at a claim. Instead of asking "is this true?" they ask "what would happen if this were true?" And if they don't like the answer — they use that as a reason to reject the claim.

But here's the thing: the truth doesn't care about your feelings about it.

Whether something is true or false has nothing to do with whether the consequences are convenient or uncomfortable. Reality doesn't adjust to what we want it to be.

Classic version:

"If evolution is true, then we're just animals with no special purpose. That's depressing. So evolution must be wrong."

This is backwards logic. The conclusion ("evolution is wrong") doesn't follow from the premise ("evolution leads to depressing ideas"). These are two completely separate questions:

You have to answer question 1 before you even think about question 2.

It also shows up in a positive direction — assuming something must be true because the consequences would be nice:

"If I pray, good things will happen to me. Good things happened to me. So praying definitely works."

Or in manipulation:

"If you don't buy this supplement, you'll get sick."

Both directions — fear of bad outcomes, or hope for good ones — can push people into believing things based on nothing but consequences.


📱 Real-Life Scroll

This one runs deep in comment sections:

Climate change:

"If climate change is real, we'd have to stop flying and eating meat and driving. That would ruin the economy. So I don't think it's that serious."

Health:

"If processed food is really that bad, then everything would be terrible and nothing would be worth enjoying. So I think it's fine in moderation."

(The "moderation" part might be fine — but the reasoning is broken.)

Conspiracy territory:

"If the government is actually trustworthy, that means I've been wrong for years and wasted my time. So they must be hiding something."

Relationships:

"If he actually cheated, that would mean our whole relationship was a lie. So it's probably just a misunderstanding."

School:

"If I actually failed this test, I'll have to retake the year. So I'm sure the teacher made a marking error."

The last one hits different when you've been there.


🔍 How to Spot It

The tell is when someone uses consequences as evidence.

Key phrases to watch for:

Ask yourself:

"Is this person giving a reason why the claim is false — or just saying they don't like what would follow from it?"

Those are completely different things.

Also watch for the reverse: when someone is motivated to believe something because of what it would mean for them. Hope and fear are powerful — and they can absolutely hijack reasoning.


💬 What You Can Do

When you catch this in a conversation:

Option 1 — Separate the questions:

"Whether it's true and whether we like the consequences are two different questions. What's the evidence for or against the claim itself?"

Option 2 — Name it gently:

"I think you're arguing from what you want to be true rather than from evidence. That's understandable — but it doesn't actually tell us if it's true."

Option 3 — Sit with discomfort:

This one's for yourself. When you notice you're resisting an idea because you really don't like where it leads — pause. That's a signal to look harder at the evidence, not to dismiss it.

Some of the most important things to understand about the world are uncomfortable. That's not a bug — it's the whole point of actually thinking.


🎯 Your Challenge

This week: find a belief you hold partly because you like the consequences.

Be honest. Do you believe something is true because evidence supports it — or partly because believing it is more comfortable?

It could be small (convincing yourself that one more episode won't hurt your sleep schedule) or bigger (a political or social belief that you've never really pressure-tested).

Write it down. Then find one piece of evidence that genuinely challenges it. You don't have to change your mind — but sit with the discomfort for a minute.

That's what real thinking feels like. It's supposed to be a little uncomfortable. 🎓
