52 Things 2020 Edition

  • We previously covered this brilliant list of 52 things learnt for 2019 and 2018.
  • Here is the 2020 edition – full of gems. A few choice examples:
  • Most cities plant only male trees because it’s expensive to clear up the fruit that falls from female trees. Male trees release pollen, and that’s one of the reasons your hay fever is getting worse. 
  • For VC companies in 2004, the average time from first contact to funding was 90 days. Today, it’s just nine days
  • Car safety laws in the US make it more expensive to have three children — women in states with mandated car seats are 0.7% less likely to have a third child. The safety measures may have saved 57 car crash fatalities each year, but caused 145,000 fewer births since 1980.
  • Developing and launching the iPod in 2001 took just 41 weeks, from the very first meeting (no team, no prototype, no design) to iPods shipping to customers.

Analysing Impact of Covid – Habits

  • One interesting approach to understanding if things will change is to look at scientific research.
  • In this paper – How are habits formed: modelling habit formation in the real world – researchers measured how long it took to form a habit.
  • They found that the median time was 66 days ranging from 15 – 254 days.
  • Exercise habits took longer to form.
  • The longer it took to form the stronger the habit was.
  • With lockdowns now lasting longer than 66 days real habit change is likely.

Games

  • A brilliant extract from a podcast with Shopify CEO Tobi Lutke quoted by Alex Danco in his newsletter (after joining the company).
  • “I’m a card-carrying member of the “video games are actually good” club. I’ve learned so many things in my life through video games … I tend to point out a few I think are extremely valuable. Factorio is one of those. It’s the one game that anyone at Shopify can expense. .. We’re building supply chains for our customers; logistics networks; and Factorio makes a game out of that kind of thinking.
  • The reason why I think video games are good is because of transfer learning. There’s a good book called The Talent Code that talks about this. There was a famous story about people analyzing why Brazilians became so much better at soccer than anyone else. And there were many reasons – it’s a system that’s reinforced by all these things – but people hadn’t found the key reinforcing mechanism that made this true. 
  • It turns out, in Brazil there was a culture of playing a pickup game, a version of soccer that was played in a much smaller space and with fewer players. And the players did all the things you need to be good at soccer, but they did them significantly more often, because there was more ball contact per person. Just because that’s a different game than soccer doesn’t mean people won’t learn soccer skills. They had way more ball contact than someone who went through the British system, by the time they entered the Premier league, for instance.  
  • But if I sit down for an evening of poker, I make these decisions every hand. And then you look at a game like Starcraft, which I think is very good, or Factorio, and in a very compressed, fun environment, follow a certain activity over and over and over again which otherwise comes around only rarely. And doing that will change your mind, and your brain, and help you be prepared for situations you could never predict.“

Danish Mink and Covid

  • Last week Denmark sounded the alarm on potentially dangerous developments related to SARS-CoV-2 virus.
  • The two worrying elements are (1) a mutation in the spike protein which could render the upcoming vaccines and antibody immunity of those already infected useless (2) a jump from animal (mink) to human.
  • This is a good summary and the press release from the Danish Serum Institute (use Google Translate) is also worth reading.
  • STAT news have a more sanguine take – arguing that there is nothing to suggest the mutated virus could have higher transmission rates or risks for humans and single mutations rarely are cause for alarm.

Analogy and Metaphor

  • “When teaching, an idea is often put forth and the students may not grasp it. It’s like sailing into the wind. So what do you do? You tack with an analogy. You move to the side so that in the end you will make progress towards a goal that can’t be reached directly. “

Product Market Fit

  • “I came across this guy, Sean Ellis. Now, Sean ran growth in the early days at Dropbox, LogMeIn, and Eventbrite. He even coined the term “growth hacker.” Now Sean found a leading indicator of product to market fit, one that is benchmarked and predictive. Just ask your users this. How would you feel if you could no longer use the product? And measure the percent who answer, very disappointed. After benchmarking hundreds of startups, Sean found that the companies that struggle to grow always get less than 40% very disappointed. The companies that grow most easily almost always get more than 40%, very disappointed. In other words, if more than 40% of your users would be very disappointed without your product, you have initial product to market fit. Now, this metric turns out to be more objective than a feeling. It predicts success better than net promoter score, and it’s not only the best way to measure product to market fit”

Asset Light

  • Suddenly, “size,” “footprint” and “incumbency” came to be understood as an expensive legacy rather than a competitive advantage. Investors wanted companies that were smarter instead of larger, as reflected in the new patois of sell-side flipbooks which now marketed businesses as “agile,” “disruptive,” “nimble” and – especially – “asset light”.
  • Nice chart demonstrating this.

Active Concentrated Portfolios

  • A thought-provoking piece (first one in the link) arguing against concentrated equity portfolios – the orthodoxy of the day.
  • Concentrated portfolios are built on the idea of “analytical certainty” which lends itself easily to “overconfidence” and “overweighting hubris”
  • Institutions that hold several such concentrated portfolios, thereby diversifying, might find instead they suffer from other forms of correlation – in terms of stock size (large cap) and style (quality or growth).
  • They will also find that the higher fees charged by concentrated active portfolios add up and don’t average down.
  • Most interestingly concentration “underweights luck” – that term most fund managers have pushed deep into their subconscious.
