In anticipation of the AZ contract publication, a quick walk through of the vaccine contract we do have (which may be different, though I doubt it) and why the Commission's argument is disgraceful

Survivorship Bias 101

History is written by the victors. But if we exclusively focus on these successes, we allow survivorship bias to distort our understanding of the world.

But what is "survivorship bias" and how does it work?

Here's Survivorship Bias 101!

👇👇👇

1/ First, a few definitions.

Survivorship bias is the logical error of concentrating on survivors (successes) and ignoring casualties (failures).

When we do so, we miss the true "base rates" of survival (the actual probability of success) and arrive at flawed conclusions.

2/ When we completely ignore failures, we lose our ability to correctly identify the differences between successes and failures.

Put simply, exclusively focusing on successes may actually inhibit our ability to identify (and replicate) the actions that led to such success.

3/ Cicero wrote on the topic over 2,000 years ago.

An atheist named Diagoras is shown portraits of people who prayed and were saved from death at sea as proof of God's existence.

Diagoras replies, "I see those who were saved, but where are those painted who were shipwrecked?"

4/ Cicero cuts right to the point - we cannot conclude that prayer led to being saved from the sea if we ignore those who prayed and then drowned.

Survivorship bias can lead to a deeply-flawed understanding of cause-and-effect relationships.

Let's look at some examples.

"The engineers on my team just want to code. They don't want to have anything to do with product. They just want specs. What do I do?"

1/n Are you asking them do to X *and* do their "day job" as defined by their managers (and frankly your roadmap) ?

If so, start there...

2/n Do they have a reason to believe that doing X will in any way improve the quality of the product and make their lives easier? Have they ever seen X "work" ?

Show don't tell.

3/n Is there average day/week a quagmire of unnecessary meetings, wading through tech debt, struggling to get *anything* to work ... and jumping through process hoops to prove their worth?

If so...no they will not have bandwidth.

4/n How do incentives work on the engineering team? Maybe they want to help, but their "grade" is determined by something altogether different.

"I'd love to, but I am on the hook to deliver [some project] this quarter to make a good impression..."

Talk to eng management.

5/n Have they had any time to practice?

Or did they get thrown into the deep end the first time they were given a shot ... expected to brainstorm on demand, be as vocal as practiced PdMs and designers, and "participate" !

Make it safe to practice. Reasonable expectations.

LEEDS LEADS CLIMATE BREAKDOWN

8 hours and 1000 flawed arguments and biased procedures later, Leeds City Plans Panel voted 9-5 for airport expansion and the false promises of economic growth.
For “what Leeds needs is a premier-league football club and a premier-league airport”
🧵

1/ There was a lot of "I do care about climate change, BUT" – followed by a lot of blah blah. Blah blah economic growth. Blah blah connectivity. Blah blah competitiveness. Blah blah Manchester. Blah blah Westminster. Blah blah offsetting. Blah blah electric planes. Blah blah blah

2/ Also a lot of "I do have sympathy for residents suffering from planes flying over their roofs at night, BUT” - followed by more blah blah.
One councillor kindly offered his advice: “the way to less noise is more planes”. Right, Sherlock. Want to try that in your backyard?🤦‍♂️

3/ The true sympathies were revealed at the end. The Panel's priority was not the well-being of those living under the flight path, nor the lives and livelihoods of threatened by climate breakdown. Their priority was a bigger, noisier airport, with a terminal in bronze-champagne.

4/ First declaring your sympathy for people’s suffering and then supporting a development that directly aggravates their suffering, is a proper kick in the face for those suffering the consequences. Like first declaring a climate emergency and then aggravating climate breakdown.

@jeffreyatucker In the end, it is all a natural consequence of a very human foible, namely that we all do everything we can to blame anybody or anything else for our problems, if we can get away with it. It's the reason why rulers start wars to squelch domestic dissent - macro and micro the same

The very notion of the germ theory of disease revolves around this and while it is good for selling medical interventions, treatments and pharmaceuticals, it is no good for either personal health, or public health in any way. We need to start looking at health on a holistic level

More of a systems approach to health would get us to see that the whole instinct to stamp out viruses, like the very counter-factual notion of "zero Covid," and other nonsense, are driven by this need to blame somebody or something else for our problems, so we can have our cake

and eat it too, i.e. we can pass the blame to others and go and kill them, be they bugs or other people (lockdowns???). The results are disastrous for health on both a personal and a public level, and we continue on a path of assured self-destruction. But times are changing, now.

Lifestyle Medicine @aclifemed provides the new paradigm, more of a systems approach to health, in which personal responsibility for our habits comes first, starting with nutrition. Immune systems become depressed by fatigue, stress, inner conflict, malnutrition and so on. Change
