COST-BENEFIT ANALYSES

The chart below shows the expected financial returns of a Russian Roulette gambler playing it multiple times.

There is no high-enough prize (nor low-enough cost) that make Russian Roulette worth it over time.

(thread, 1/N)
2/ Of course, there are reasons for which one would want to play Russian Roulette once.

But Russian Roulette cannot be a long-term strategy.
And it's not about cost-benefits.
3/ In a previous thread posted today, I compared GMOs to Russian Roulette.

Both come with a risk of ruin, and therefore none can become a strategy.
4/ I later deleted that thread, because I didn't want to give the wrong impression that "$0 payout" and "death of the ecosystem" are the same thing.

They are not, and I did not intend suggest that.
5/ What I wanted to show, is that one cannot take a single-gamble cost-benefit analysis and extend it to a repeated set of gambles.

This is a well-known phenomenon, but I found the RR chart to pass the point very well.
6/ This is because it is my impression that we are able to acknowledge that "repeated exposure to ruin means inevitable death"

but still, in our brain, it doesn't cancel the visceral thought that "the benefits might be worth the risk".
7/ I found this chart very good at passing the point that not only the worst-case scenario is bad, but that any realistic good-case scenarios are bad too.

I recently got a small grant (courtesy of Kanro, Vitalik Buterin's foundation) to produce some educational materials regarding the pandemic response.

These 10 one-pagers are the first batch of educational materials.

Any feedback?

Some more background about the one-pagers. They are meant for people who are already onboard with the need to properly react to an eventual future pandemic but don't have the vocabulary or examples to explain to others what they can do and why.

What do I think an educated society means?

Nothing about graduation rates (literacy rates, yes).

Instead:
– Knowing what matters for society to work well
– Being able to find a value-adding role in society
– Having learned that personal improvement is achievable

Not banal

1/6
1) Knowing what matters for society to work well

Things such as:
– What brings prosperity?
– What did countries that were wealthy and democratic do (or didn't do) that caused them to become poor or totalitarian

Seems banal, but…

2/6
…we only discuss how good it's to be prosperous or democratic without discussing how to get there or how not to fall back to the default state (poverty / absence of rights)

BEYOND THE CHECKLIST

A problem of many organizations is that they are aware of the needs of employees (impact, recognition, growth, fair salary, etc) but fulfill them as they would with a checklist: let's do this superficially, checked, done.

Some examples (& solutions) ↓

1/8
Example #1: recognition.

Many companies and managers know that employees want recognition.

But they fulfill this need in a very superficial way. With a small internal award, a certificate, etc. Top red flag: it's HR-driven and/or feels cringe.

2/8
The alternative:
– make it personal: it should come from the boss or the boss' boss.
– make it congruent: a moment of recognition followed by a year of no recognition feels (and likely is) fake.

Whenever we desire an outcome but not the actions that would make us achieve it, we end up with inaction, busywork, shortcuts, excuses, and, ultimately, frustration.

(a thread of highlights from the first chapter of my book "The Control Heuristic")

You probably do not have a decision-making problem, but an action-taking one

2/14 Image
Decision-making is not the same as action-taking.
The cortex is mostly responsible for taking decisions, and the ~basal ganglia determines whether we act on our decisions.

TIPS FOR EFFECTIVE DELEGATION

1) Minimize the chance of misunderstandings:

Explain:
– what's too little
– what's too much
– common mistakes
2) Explain why you need it done.

Not who asked for it. What it is for. What happens if it's not done. (And what happens if it's not done well enough.)

Tasks whose rationale isn't explained relevantly are done badly and/or at higher emotional cost
3) Pre-empt inaction and failure.

Ask them and yourself:
– Why might they not take action?
– Why might they take action and yet fail?

Footnotes are my favorite feature of my book Ergodicity (from which the screenshot below is taken).

In fact, there’s plenty of bolded text in the footnotes.

A few examples in this thread. Image
