Deep Dive on Biases that Ride on Emotion
Last week we looked at how cognitive biases sneak into our thinking. They often operate below the surface, just outside our awareness.
This week, we’re zooming in on a specific set of biases: those that ride on emotion.
These are the ones that show up when you’re angry, anxious, energized, or under pressure. They feel like moments of clarity or intuition, but they’re actually just brain chemistry.
That’s because emotions don’t just influence our thinking, they re-wire it in real time. When emotions take over, we become far more vulnerable to bias.
Let’s take a quick look at why that happens.
Why emotions create cognitive vulnerability
The brain systems that process emotion and stress are physically different from the ones that handle rational thought. When one gets activated, the other gets suppressed.
I’m not a neuroscientist, but from what I’ve learned over the years:
- The amygdala acts like a smoke detector, scanning for threats.
- When it detects one (real or imagined), it signals the "HPA Axis" to release hormones like cortisol and adrenaline.
- These hormones re-activate the amygdala so that it can remain highly alert to threats.
- These hormones suppress the prefrontal cortex, where rational thoughts occur, because that system is too slow when fighting for survival.
That whole system still operates even when we’re not fighting for survival, which can make things a little wonky.
Sometimes it turns on just because Becky (or Bob) said something that threatened our ego, and now we’re all like, “Let’s go!” 😡
Emotions start running through our body.
The result? The amygdala is amped up, and rational thought is shut down. You’re more reactive, less reflective, and far more vulnerable to biases.
Cultivating Emotional Intelligence in Yourself
If emotions can hijack our thinking that easily, what do we do about it?
That’s where awareness and emotional intelligence come in. They’re the defense against emotionally-driven bias.
Luckily for us, just like the amygdala can suppress the prefrontal cortex, the prefrontal cortex can suppress the amygdala! It’s just a much harder task because it’s not automatic. It takes energy - and practice.
Awareness and emotional intelligence are the 1-2 punch to counter the emotional hijacking.
- Awareness is just going, “Hey, I’m feeling something in my body right now.”
- Emotional intelligence gives you the language to label the emotions.
Over time, instead of trying to throw down with Becky and Bob - or your spouse, colleagues, friends, and family - you can be like, “Oh, something’s going on with my body. I’m feeling angry. Why is that?”
With enough practice you get much better and faster at recognizing when you’ve been hijacked by your emotions. You learn what triggers you and why.
Instead of reacting to your environment, you can reflect and figure out the most constructive path forward. You create space between stimulus and response.
That moment of reflection is where your prefrontal cortex comes back online - and with it, your ability to make better, clearer, more intentional decisions.
The Anti-Bias Toolkit: Part 2
Let’s look at some of the specific cognitive biases that love to sneak in when emotions are running high.
Even if you miss the subtle emotional impact on your body, you might be able to recognize some of the language used when under the influence of these biases, so you can deploy countermeasures.
1️⃣ Affect Heuristic
What it is: The tendency to make decisions based on how something feels emotionally, rather than what you objectively know.
Examples:
- Marketing: A well-designed website or logo makes a company seem more trustworthy, even if the product is unproven.
- Hiring: You get a “good feeling” about a candidate and gloss over red flags.
- Investing: You feel good about a company, so you invest in its stock without checking fundamentals.
Why it matters:
- It leads to decisions that feel right but are misaligned with reality.
- Emotions create cognitive shortcuts that feel like intuition but can override facts.
- It plays a key role in moral panic, mispricing risk, and irrational optimism or fear.
- This bias is subtle because it disguises itself as “intuition.”
How to spot it:
Ask yourself:
- “How would I assess this if I were feeling neutral or calm?”
- “Would I make the same call if I had slept better / wasn’t rushed / wasn’t annoyed?”
- “If someone else delivered the same idea in a dry tone, would I trust it as much?”
Also look for:
- Making snap decisions when excited or frustrated.
- Equating likability with credibility.
- Using “it just feels right” or “off” as the primary reason.
How to counter it:
- Emotional Intelligence: Name the feeling. Even just saying “I’m feeling anxious” creates distance between emotion and action.
- Decide during a different mood: If a decision feels high-stakes or emotion-heavy, wait and revisit it when your state has shifted.
- Use structure: Set clear evaluation criteria before you encounter the decision. This helps anchor you to logic, not vibes.
2️⃣ Backfire Effect
What it is: Where being shown evidence that contradicts our beliefs causes us to believe more deeply in them.
Examples:
- Feedback: You get critical input on your work and immediately feel the urge to defend it instead of explore it.
- Ideas: Someone challenges your strategy, and you find yourself arguing harder, not listening.
- Beliefs: You read something that contradicts a position you’ve taken, and your first impulse is to discredit the source.
Why it matters:
- It makes conversations unproductive, especially around controversial or high-stakes topics.
- It prevents learning, adaptation, and course correction.
- It turns feedback into a perceived threat instead of a tool for improvement.
How to spot it:
Ask yourself:
- “What part of me feels challenged? Is it my ego, or my reasoning?”
- “Why am I feeling so reactive to this feedback?”
- “Do I want to learn, or just win this argument?”
Also look for:
- Emotional heat rising during disagreement.
- Discrediting the messenger instead of evaluating the message.
- Feeling the need to “prove” you’re right rather than consider new info.
How to counter it:
- Pause and breathe: Let the emotional reaction pass before responding.
- Stay curious: Replace judgment with genuine curiosity. What else could I learn here?
- When receiving feedback, pause and ask: “What part of this could be true?”
3️⃣ Focusing Illusion
What it is: Fixating emotionally on one element of a decision, leading to an overestimation of the significance of that factor while neglecting other relevant aspects.
Examples:
- Job Search: You obsess over salary and ignore role fit, culture, or growth.
- Conflict: One colleague frustrates you, and suddenly everything they do seems wrong.
- Prioritization: A minor issue becomes your sole focus, blocking out bigger strategic needs.
Why it matters:
- Emotionally charged focus skews your judgment.
- You can miss tradeoffs or fail to balance competing factors.
- It causes tunnel vision, even in high-stakes decisions.
How to spot it:
Ask yourself:
- “What am I obsessing over? What am I overlooking?”
- “If I had to list five things that matter here, what would they be?”
- “Will this still matter in a week, a month, a year?”
Also look for:
- Emotional urgency around a single issue
- Repeating the same point to yourself or others
- Neglecting tradeoffs or context
How to counter it:
- Zoom out: Make yourself list out multiple decision factors, not just the one in focus.
- Seek contrast: Ask someone else what they think you’re ignoring. (this is a good AI use case, btw!)
- Time travel: Imagine looking back at this choice a year from now. What matters then?
“Nothing in life is as important as you think it is when you are thinking about it.”
4️⃣ Authority Bias
What it is: When you give more weight to someone’s opinion because of their perceived authority, especially in moments of uncertainty, fear, or stress.
Examples:
- Workplace: A senior leader supports a plan, and you suppress your concerns even though something feels off.
- Mentorship: You follow advice from someone you respect, without thinking critically about whether it applies to your context.
- Crisis Mode: In a stressful situation, you defer to the most confident voice in the room without checking assumptions.
Why it matters:
- You risk outsourcing your thinking to others.
- Expertise is not equal to infallibility.
- It can suppress dissent and result in blind spots for teams and individuals alike.
How to spot it:
Ask yourself:
- “Am I agreeing because the idea is strong, or because the person is?”
- “Would I trust this advice if it came from someone less experienced or respected?”
- “Is there space for disagreement here, or are we just nodding along?”
Also look for:
- Staying quiet around strong personalities.
- Citing someone’s title or track record instead of the merits of the idea.
- Avoiding critical debate out of politeness or fear of appearing disrespectful.
How to counter it:
- Separate idea from person: Strip names and titles. Judge the content alone.
- Invite dissent: Ask yourself (or others), “What could be wrong with this?”
- Cultural design: Create norms that allow you to respectfully challenge authority when stakes are high.
Bringing it All Together
Emotions aren’t an issue. They’re data.
But it's fast and possibly overwhelming data! 🤣 Immediate, visceral, and often misleading data if left unexamined.
When emotions flare up, they narrow our field of view. They can make a single idea feel urgent, a shaky opinion feel like truth, or a familiar voice feel unquestionably right. That’s when biases can get mistaken for insight.
The solution isn’t to suppress emotion. It’s to be aware of it.
The moment you pause to say, “Something’s happening here. What is it?”, you create a gap. And in that gap, you regain your power to think clearly.
You reclaim your thinking. You widen your lens. And you give yourself a better shot at making decisions unclouded by emotion.
Call to Action
This week? Feel your feelings!
When you’re making a decision, notice where emotions show up in your body. Tightness? Holding your breath? Tingly sensations?
That’s data.
Pause. Name it. Then check your thoughts against the four emotional biases: affect heuristic, backfire effect, focusing illusion, and authority bias.
Let me know what you find!
Next week we’ll take a break from cognitive biases before returning with part three: biases that pop up in social contexts.
