Decisions Under Emotion

You’ve felt it. That moment when you know what to do. The certainty is overwhelming. The path is obvious. You act immediately.

Later, you wonder what you were thinking. Because clearly you weren’t.

Emotions don’t just color how you see things - they can completely hijack your choices. The thinking part of your brain gets shoved aside while the feeling part takes over. Understanding this is key to thinking clearly.

Emotions Aren’t the Enemy

Let’s be clear: emotions aren’t bad. They’re information. They’re motivation. They’re what makes life meaningful. A life without emotion would be a life without meaning-and probably wouldn’t last long, since emotions evolved to keep us alive.

The problem isn’t feeling emotions. It’s letting them make decisions they’re not equipped to make.

Fear is useful when there’s an actual threat. It’s less useful when it stops you from sending a reasonable email to someone who might not respond the way you hope.

Anger is useful for setting boundaries, for signaling that something is wrong. It’s less useful for composing that reply at 2 AM that you’ll regret by 2 PM.

Excitement is useful for pursuing opportunities. It’s less useful for evaluating whether an opportunity is actually good.

How Emotions Hijack Thinking

When you’re in a strong emotional state, your brain changes how it processes information:

Your attention narrows. You focus intensely on the emotional trigger and miss everything else. It’s like having tunnel vision for whatever upset you.

Your time horizon shrinks. The future barely exists. Only the present moment and immediate relief matter. Long-term consequences become theoretical abstractions.

Your options collapse. Complex situations suddenly feel like they have only one possible response. Binary thinking kicks in hard.

Your confidence inflates. You feel absolutely certain about things you’d normally question. The doubt circuitry goes offline.

Your empathy shifts. Others become obstacles, enemies, or irrelevant. Their perspectives stop mattering.

This is why choices made in anger, fear, or excitement often make no sense later. You were working with a different brain - or really, a different setup of your brain, with less thinking power and more feeling power.

The Danger Zones

Anger

Anger feels righteous. You’ve been wronged. Justice demands action. The other person deserves whatever you’re about to do.

Here’s the uncomfortable truth: anger is your enemy, even when it feels like your friend.

Your brain gave you anger to help you survive. In the ancestral environment, anger was useful for intimidating rivals, defending territory, and signaling that you shouldn’t be messed with. It served a purpose.

But anger is a blunt instrument. It’s like having a sledgehammer in your emotional toolkit-sometimes appropriate, but devastating when used on problems that need a scalpel. Modern life rarely presents situations where rage is the optimal response. Yet the anger system fires anyway, because it evolved before email, before professional consequences, before situations where losing your temper could cost you your career.

This means you have to actively fight against your own anger. It’s not serving you. It’s an outdated survival mechanism that’s been co-opted by your ego. The anger feels like it’s protecting you, but it’s usually just making things worse.

Decisions made in anger:

Sending that email you can never unsend
Making that comment you can never untake
Quitting dramatically when you needed the job
Ending relationships that were worth saving
Starting fights you can’t win

The regret pattern: “I had every right to be angry, but I wish I hadn’t…”

What anger wants: To hurt, to punish, to win, to restore status, to make them pay What you usually want: To solve the actual problem, to protect yourself, to be heard and understood

These are different goals. Anger rarely achieves what you actually want. Managing your anger isn’t weakness-it’s recognizing that you’re smarter than your limbic system.

Fear

Fear screams that something terrible is about to happen. Safety requires immediate action. There’s no time to think-thinking is what prey does before they get eaten.

Decisions made in fear:

Avoiding necessary conversations indefinitely
Not taking opportunities you’ll later wish you had
Agreeing to things you don’t want just to make the scary feeling stop
Running from manageable problems until they become unmanageable
Over-preparing for unlikely disasters while ignoring probable ones

The regret pattern: “I was so worried about X that I didn’t do Y, and now…”

What fear wants: To avoid all possible threats immediately, at any cost What you usually want: To handle actual risks proportionally while still living your life

Excitement/Euphoria

Excitement feels expansive. Everything seems possible. Concerns feel like pessimism. Caution feels like cowardice. Anyone who raises objections is a buzzkill.

Decisions made in excitement:

Signing up for things you won’t finish
Making promises you can’t keep
Spending money you don’t have
Committing to relationships too fast
Starting projects without planning

The regret pattern: “It seemed like such a good idea at the time…”

What excitement wants: To capture this feeling forever, to say yes to everything, to never come down What you usually want: Something that’s still good after the neurochemical high fades

Hurt/Rejection

Feeling hurt or rejected triggers a desperate need to relieve the pain. Anything that promises relief looks attractive. Judgment goes out the window.

Decisions made when hurt:

Seeking validation from the wrong sources
Lashing out at people who didn’t cause the hurt
Making dramatic changes just to prove something
Settling for less than you deserve because any acceptance feels like rescue
Pushing away people who actually care about you

The regret pattern: “I was so desperate to feel better that I…”

The Time Buffer

The simplest intervention: Wait.

Most emotional decisions don’t actually need to be made immediately. That’s the emotion talking-it wants immediate action because waiting feels intolerable. But that email can wait until tomorrow. That conversation can happen next week. That purchase can sit in your cart overnight.

Rules of thumb:

Angry: Wait 24 hours before responding to anything
Fearful: Wait until you can articulate the actual risk in specific terms
Excited: Wait until you can articulate the downsides and you still want to proceed
Hurt: Wait until you’ve talked to someone uninvolved

Time alone won’t solve everything, but it changes the brain you’re using to decide. Tomorrow’s brain is different from today’s brain. Use the better one.

Recognizing the Hijack

Signs your emotions might be driving:

Certainty without analysis. You know what to do, but if someone asked you to explain your reasoning, you couldn’t. You just know.

Urgency without deadline. It feels urgent, but there’s no external reason it must happen right now. The urgency is internal, not situational.

Simple solutions to complex problems. The situation is objectively complicated, but your answer feels obvious. That’s suspicious.

“I don’t care about consequences.” You’re willing to accept any fallout. This is a red flag, not a sign of conviction. Future you will care about consequences.

Physical symptoms. Racing heart, clenched jaw, tight chest, restless energy, shallow breathing. Your body knows you’re in an emotional state even when your mind insists you’re being “rational.”

Practical Techniques

Name the emotion

Literally say (or write): “I’m feeling angry/scared/excited about X.”

This turns on the thinking part of your brain and calms the feeling part. It sounds too simple to work - just saying what you feel? - but studies back it up again and again. Naming your feelings uses the same brain parts you need for thinking, which pushes back against the emotional ones.

Check the story

Emotions come with narratives. They don’t just make you feel things; they tell you stories about what those feelings mean.

“She disrespected me on purpose.” “If I don’t act now, I’ll lose everything.” “This is the opportunity of a lifetime.”

Write down the story. Then ask: “Is this definitely true? What else might be true?” Usually the story is one interpretation among several, and not necessarily the most accurate one.

Consult future you

Ask: “How will I feel about this decision in a week? A month? A year?”

If you can’t even imagine future-you’s perspective, you don’t have enough distance from the emotion yet. Wait until you can.

Find someone calm

Talk to someone who isn’t emotionally involved. Not for them to decide for you-just to borrow some of their perspective.

Their job isn’t to agree with you. It’s to help you see what you can’t see right now. If they say something that makes you defensive, that’s worth paying attention to.

Write before acting

If you must respond while emotional, write it out first. Write the angry email. Write the fearful objection. Write the excited commitment.

Then save it as a draft. Don’t send. Read it tomorrow.

You’ll often be grateful you didn’t send it. And if tomorrow you still want to send it, at least you’ll be sending it with a clearer head.

After the Emotion

When the emotion passes, resist the urge to pretend it didn’t happen. Instead:

Acknowledge what you felt. The emotion was real and probably had valid roots. Something triggered it.
Evaluate what it wanted. What was the emotion trying to protect or pursue? What need was it signaling?
Consider proportional action. Is there a calmer way to address the underlying need? Usually there is.

The goal isn’t to stop feeling. That’s not possible and wouldn’t be good anyway. The goal is to respond to what’s happening rather than react to how you feel - to let emotions give you information without letting them make your choices.

What’s Next

Part 4 covers confirmation bias in depth-our tendency to seek evidence that supports what we already believe while ignoring evidence that contradicts it. This is the bias that makes all other biases harder to escape, because it prevents you from noticing you’re biased.
