My Fear Heuristic

My friends and family call me "risk tolerant". I wasn't always this way. It is the result of a 3-year-long scientific experiment.

You must do everything that frightens you…Everything. I’m not talking about risking your life, but everything else. Think about fear, decide right now how you’re doing to deal with fear, because fear is going to be the great issue of your life, I promise you. Fear will be the fuel for all your success, and the root cause of all your failures, and the underlying dilemma in every story you tell yourself about yourself. And the only chance you’ll have against fear? Follow it. Steer by it. Don’t think of fear as the villain. Think of fear as your guide, your pathfinder.

The Tender Bar by J.R. Moehringer

When I was 18 I discovered a useful heuristic. Whenever I didn't know what to do I would pick whatever not-obviously-stupid[1] option frightened me the most.

My indecisions always centered around choosing between a scary unpredictable option and a comfortable predictable option. Since the comfortable option was always predictable, I always knew what the counterfactual would have been whenever I chose the scary option. If I chose the scary option then I could weigh the value of both timelines after the fact.

As an experiment, I resolved to choose the scarier option whenever I was undecided about what to do. I observed the results. Then I recorded whether the decision was big or little and whether doing what scared me more was the right choice in retrospect. I repeated the procedure 30-ish times for small decisions and 6-ish times for big decisions. If I were properly calibrated then picking the scary option would result in the correct choice 50% of the time.


  • For my 30-ish small decisions, picking the scary option was correct 90% of the time.
  • For my 6-ish big decisions, picking the scary option was correct 100% of the time.

The above results underestimate the utility of my fear heuristic. My conundrums were overwhelming social. The upsides earned me substantial value. The downsides cost me trivial embarrassments.

I terminated the experiment when my fear evaporated. The only things I still feared were obviously stupid activities like jumping off of buildings and unimportant activities like handling large arthropods. I had deconditioned myself out of fear.

I didn't lose the signal. I had just recalibrated myself.

This post would be strongly improved by 3 examples of decisions you made differently due to this heuristic.

Seconding this, examples would be extremely helpful here (they could be anonymized if you don't want to share personal details)

I agree. Someone else should replicate my experiment. I give prior advance permission to self-promote the results in this comments section.

I also had this heuristic for a while. It helped me a lot and gave me a lot of growth. However, it also made me make some bad social moves that didnt turn out well for me.

Eventually I stopped using this heuristic, and instead started viewing things that I feared as things to process and integrate instead of face.

How do you make the difference between something you fear and something you suspect will be detrimental? Like, say, befriending someone who freaks you out, or entering a shady scheme?

Befriending someone who freaks me out and entering a shady scheme are both obviously stupid. If something is obviously stupid then this heuristic is overruled.

I use this heuristic only for marginal cases where my calculated expected value is equal for both options. (The net expected detriment of either choice compared to the other is zero.) Only if the previous condition is satisfied do I then check which of the two options triggers greater fear. Fear is an emotion. I imagine both futures and observe my emotional reaction.

I think you should make this explanation part of the article. It's crucial.

I'm exploring a practice of what I'll call "peer preview," trying to assess the value a post provides to its audience, what other valuable projects could emerge from it, and how it might be viewed a year from now.

There's a lot of advice and vivid descriptions of anxiety out there, and the benefits of overcoming it. But it's rare to get a quantitative perspective like this. The documentation seems like a lightweight technique with real potential benefits. I wonder if it's a common prescription.

It makes me wonder how many people who don't perceive themselves as neurotically timid or anxious have actually just managed to shield themselves from ever encountering anxious triggers. I can think of several things that seem anxiety-provoking, that might be a happy addition to my life, and which don't actually cause me anxiety because I so thoroughly avoid them. I can also see how a tacit part of many relationships is identifying what makes each other anxious, and securing tacit agreements that you will avoid those anxious triggers forever.

I'd be interested in writing about relationships that delves into the nuances of how to cultivate friendships and romantic relationships in which there's a conscious mutual understanding of that "anxiety avoidance" dynamic, and an explicit agreement to find ways to shift into a "do what scares us" paradigm.

Note: In response to feedback, I'm removing a portion of this comment that might not be constructive.
