Why smart people come up with bad ideas

I recently made an observation, a very smart person I know blurted out an idea in a meeting and was convinced the idea ended the conversation.

The person who blurted out the idea is very smart, but the idea was not very good. I’ve seen great organisations implement bad ideas many — many — times. But this time I asked myself: why does this happen? What causes brilliant people to jump on bad ideas, and take decisive actions that are clearly not great?

My hypothesis was that stress causes us to believe that the real linchpin in a situation is having an idea, any idea, of what to do next. As if an idea was all it took to solve problems.

I wrote a Twitter thread about it to see if anyone else had similar experience. It turns out a lot of people do.

I’ve made an observation recently, and I’d love to hear if you’ve seen the same? People who are stressed (very busy) tend to believe ideas are more valuable than they really are.

Turns out a most people see this behaviour

Some very smart people chimed in with their own experiences and it seemed like I had stumbled upon an important insight. Then my friend Fredrik offered this insightful reframe of the behaviour:

It could be rephrased like this, people who are very busy think in basics. Speed at the cost of depths and I wholly agree with your observations

Fredrik Paulin

This reframe is powerful because it removes the emotional component from the idea completely. This behaviour is not something that some people do. It’s not an error that pops up as the side effect of fuzzy thinking. It’s a classic error that is innate to humans, blank and white thinking.

To avoid this behaviour myself in the future I want to define this problem as follows.


Stress causes humans to think in basics. Which means we’re grasping for straws, and an idea that seems to solve the problem, no matter how badly, is preferable to not making a decision.

A side effect of this behaviour is a tendency to believe ideas are more valuable than execution. Because by choosing an idea, the stressed human believes they have taken action.

Ten days without coffee

Last year my fiancé Agnes lived without caffeine for 10 days to see how it would affect her, I wanted to try it myself.

Her research showed that 10 days should be enough to go completely off caffeine, including withdrawals.
This intrigued me, as an avid coffee drinker since high school. I’ve never thought of giving coffee up, I haven’t seen the point. But I have to ask myself, am I really enjoying coffee, or is it an addiction? Can I even function as a human without caffeine, or will I get terrible withdrawals? Time to find out.

I’m doing this during the darkest months of the year in Stockholm (Sweden), so we only get a few hours of light every day. Will I stop being productive? Will I snap at people? I’m a little worried to be honest, but also excited to find out!

Day one, Monday 2021.01.18

Almost lunchtime and so far so good. The morning wasn’t bad at all but I’m feel a little drowsy and slow.

To be clear, I’m not naturally a morning person, but I am really strict with my sleep schedule because I had insomnia growing up.

Afternoon meetings were really hard to focus on. Felt oddly warm and comfortable, and almost dozed off more than once.

Day two, Tuesday 2021.01.19

Morning felt fine. Felt sluggish at lunch, but that could just be my normal lunch time coma.

Feeling some slight headache coming and going. And warmer than usual. I’m naturally always cold. Temperatures under 25C is just not for me. But I don’t know if caffeine withdrawal can have this effect?

The headache persisted the entire day. Just getting slowly worse until I went to bed.

Day three, Wednesday 2021.01.20

Not a great day. I woke up at 4am from a headache and couldn’t fall back asleep. Felt ok all morning, but then after lunch something strange happened…

I feel great. I feel awake. Like I’ve just had a pot of coffee without the jitters. This is really odd.

Day four, Thursday 2021.01.21

I feel great! Not what I’d call energetic, but I’m not tired at all. I feel calmer, and warmer, than usual. This is actually quite great, though I do miss drinking coffee.

I can’t believe how many drinks have caffeine in them. The only warm drink without caffeine I’ve found was some fancy red tea that smells and tastes like bubble gum. They haven’t been a great substitute… Also its warmer today which helps.

Day five, Friday 2021.01.22

I don’t feel as good as yesterday. But I still feel surprisingly springy in the morning. I discovered they serve decaf espresso at a local coffee shop, which really helps still the hunger for drinking something warm.

Day six & seven, weekend

I felt great. Energetic, focused, and calm. Woke up hungover one morning and that was annoying but still no real craving for coffee.

Day eight, Monday 2021.01.25

I slept well. Woke up early and had a massively productive day. Was focused without hardly a break from 8am to 9pm. And I felt great!

Day nine, Tuesday 2021.01.26

Slept badly and really feeling like I need a coffee. But oddly, as the days goes on, I need it less and less. Actually feeling pretty springy and energetic now at 2pm. This was rarely the case when I was drinking coffee.

Day ten, Wednesday 2021.01.27

That’s it, this is the last day. I did it! And it’s strange.

Feels like this wasn’t as hard as I had thought it would be. Almost like I wanted there to be more problems? Which is a strange thing to want.

I feel great though. I feel rested, and despite a few bad nights I’m not very tired during the day.
When I do get tired, it feels more like a calm sleepiness rather than the abrupt mental cliffs I experienced before.

I’m excited about having coffee again. But also kind of worried how it will make me feel. I’ll have to follow this up with a post about going back on coffee.

Watching films

For the last two years I have been trying to be mindful about what media I consume. I’ve been trying to only watch, and listen to, what I want to. Not because I should keep up, or because it’s routine, or because I need the distraction.

This has resulted in less podcasts, turning off my Netflix subscription, and instead coming back to classics. Or sometimes, simply not doing anything.

I’ve seen more black & white films these last two years than I’ve seen Netflix shows. And I think it’s been good a thing

Yesterday we couldn’t find “Blood and Sand” with Rita Hayworth. While searching we realized we hadn’t seen “Parasite”, the Korean film that took the word by storm in 2019. So we saw it. And I’m extremely happy we did. It’s an amazing film, and work of art.

Time is a great judge of what is worth your attention, and what isn’t. But the Lindy-effect can’t filter out what is great today.
I think I might need to sample a bit more current culture.

What are we consuming that broadens our minds?

Something the Farnam Street newsletter got me thinking about today. Read the whole thing here.

““[M]y worry is that … you won’t put enough really excellent stuff into your brain. I’m talking about what you might call the “theory of maximum taste.” This theory is based on the idea that exposure to genius has the power to expand your consciousness. If you spend a lot of time with genius, your mind will end up bigger and broader than if you spend your time only with run-of-the-mill stuff. The theory of maximum taste says that each person’s mind is defined by its upper limit—the best that it habitually consumes and is capable of consuming. … In college, you get assigned hard things. You’re taught to look at paintings and think about science in challenging ways. After college, most of us resolve to keep doing this kind of thing, but we’re busy and our brains are tired at the end of the day. Months and years go by. We get caught up in stuff, settle for consuming Twitter and, frankly, journalism. Our maximum taste shrinks. Have you ever noticed that 70 percent of the people you know are more boring at 30 than they were at 20?.””

2019 in review

2019 promised to be a year of celebration and positive change. It turned out to be tumultuous in the extreme. This has .been among the hardest, if not the hardest, year I’ve even experienced. Strangely, it also contained some fo the happiest moments of my life.

I’ve never cancelled so many trips. I’ve never had so much cause to celebrate. And I’ve never been this close to death, both literally and figuratively.

Timeline of Events


January started with the most extreme event. I was rushed to the emergency room, diagnosed with a blood cot around 30cm (a foot) long. And I don’t believe I would’ve gone to the emergency room if Agnes had not insisted. I tell her she saved my life, but she doesn’t believe me.

February was uneventful and a bit scary.

March disappeared in prepping for the years big adventure.

April we went to Tokyo for 10 days. To see the cherry blossom, celebrate my birthday, and fulfil our shared lifelong dream of visiting Japan. I also took the chance to propose. Luckily she said yes. And suddenly the year didn’t seem so bleak any more.

May brought the first wave of summer northern Europe, we hung out on the balcony. Took extra long walks with the dogs. Saw more friends and even visited Berlin together for the first time!

June was spent working hard, visiting outdoor bars, and rushing up to the northern parts of Sweden to prep and then celebrate Swedish midsummer. Despite a lot of bad planning, we had a great time!

July was vacation time. Desperate to rest up from a stressful first half of the year, we tried to do too much and ended up tired like never before. We also spent a ton of time watching old movies on our balcony and people watching on rooftop bars. So it was not a bad time.

August already started turning cold. Spiff, our dog, had a terrible month health wise. We spent a lot of time in the archipelago, enjoying the last of summer.

September turned out beautiful. So we spent more time in the archipelago, with Agnes’ parents and their new puppy. I also joined the bachelor party for my dear old friend Douglas. Sadly, we also had to say goodbye to our little dog.

October was mostly about work, Stockholm was already cold, but beautiful. Oh and Douglas got married, which we celebrated in style.

November went by in a blur. Tons of work. We did manage to hang out with my parents a bit though. And on the tail end, we saw the years first snow.

December was a month of celebration this year. Agnes turned thirty, which we celebrated at least three times. We also went full on Christmas mode and loved every moment of it. Oh and I published my first book.

What I Learned

It’s hard to even know where to start after a year like this. With so much death, and so much celebration, I should’ve learned a ton of things I guess.

Truthfully. I haven’t had much time to think deeply about things. So I think I learned less this year, than last year.

I did relearn, or unlearn, a few things of note:

Life really is short. Every time you talk to someone, it may well be the last. So don’t rush it, brush it off, or force yourself through it. Every Christmas is the last Christmas like it. Really listen. Do the thing properly or not at all. And hug your loved ones.

Focus means doing the boring thing. Fun and stress are distracting, and yourself is the easiest person to distract. Do the boring thing. The slog. What is meaningful long term is what you’ll look back at as meaningful.

Take risks. This is the only way we grow. Rest, yes. But don’t get comfortable. Nothing happens when you’re comfortable.

Health & Fitness

No photo this year. Because of the blood clot I’ve trained a lot less this year than I would’ve liked to. I’m also the fattest I’ve been for many years (which is stil pretty thin). And this is affecting my mental state way more than I like to admit. It’s strange how discretely vanity builds up in ones own self image.

I have on the other hand started drinking way less, and slowly becoming more mindful of how I’m dealing with stress. So the year is not all wasted. And I’m looking forward to training harder in 2020.

Who you travel with

In life, it’s not where you go – It’s who you travel with.

— Charles Schulz

I’m starting to realise this is true more and more. Not only does this apply to my own ideas about applying minimalism in relationships (keep the ones that spark joy perhaps?), but also to what sort of person I want to be.

I will be a part of hundreds of lives during my time, some shortly for a dinner or a smile in a store, some deeply, it’s worth really thinking deeply about what sort of person I want to be in those lives.

How does Focus work?

If you’re interested in personal performance like me, no doubt you’ve read a lot about focus and energy management the last few years. New Studies claim that focus and willpower is like a tank of gas that runs dry if you use it to much during the day. Other New Studies shows that meditation (the practice of focusing and refocusing for short periods of time) increases focus.

So which is it? How does focus work? I think their both right.

Focus seems to work very much like a muscle, if you deliberately practice it, you can focus deeper and with more control (i.e. it gets easier to start and stop focusing). But it also seems to work a lot like endurance, the more time you spend focused, the less mental energy you’ll have at the end of the day.

Which is why I try to focus deliberately, constantly nudging myself when I get distracted, and take resting very seriously. You can’t work with perfect focus forever. You might be able to effect how much you can focus, but always be aware of your limits. When I step beyond my limits, I get annoyed, cranky, feel frustrated about not getting anywhere, and spend even more energy that I don’t have. It’s a slippery slope.

How do you manage your focus?

Blood clot watch

In January on 2019 I was shocked to find myself with a foot long blood clot in my upper thigh to lower abdomen. Deep vein thrombosis usually affects people in their senior years, and correlates pretty well with being overweight and smoking.

I’m fitness athlete thin and I’ve never smoked. I was 34.

I’ve been on blood thinners ever since, and my body is supposed to solve the issue without any direct intervention. Since the blood clot is a partial blockage of a vein, we apparently don’t measure the clot itself, that would be too costly for the free healthcare system of Sweden. Instead we measure the circumference of the leg. The swelling should correlate pretty accurately with the remaining size of the clot.

Being the person I am, I naturally measured my leg every morning to track any progress. I figured it’s worth sharing. This is my blod clot watch, updated daily. When the blue line hits the bottom of the chart, I should be back to normal. The red line is a trailing average of 7 days to help show the progress.

Vacation & Proposals in Tokyo


I’m in Tokyo for a couple of weeks with Agnes, and I’m having a wonderful adventure, but also the first proper vacation I’ve ever had. No real work for the entire period. A few calls, a few drinks, and a few emails. But no planning, no deadlines to keep, nothing. Besides feeling weird, it’s also making me spontaneously bubble with ideas. Can’t wait to start working again. But I’m also really happy to see what a little rest does to me.

Also took the time to propose to Agnes. It was a surprise to her, but a 6 month long plan for me. It all worked out amazingly, because she said yes.


What are you optimizing for?

A thought struck me today while rushing from the my doctors appointment to my office. I was listening to a podcast and checking out the stock market. I was distracting myself from a pretty dreary subway ride. But I was also using the time to be productive, plan out my tasks for the afternoon so that I could optimise my time.

Todo lists. Email. Quick meetings. Lunch at your desk. 6 minute abs. Fast Food. It’s all about optimising our time. Finding a way to cram more stuff into our days.

The thought that struck me was; what am we optimizing for?

One day you will be scanning the headlines and listening to a podcast in 2x the speed, and that will be it. That was life. Optimised to the extreme. Forcedly pushed into ever longer caffeinated days. But optimised for what?

I think I’ll take my dog for a slow walk. After that I might have a glass of wine with the love of my life. Maybe call my mom. But whatever I do tonight, it will be because I wanted to, and unoptimised.
