Cognitive Bias in Forensic Pathology Decisions was published today by Journal of Forensic Sciences

From the abstract “We examined all death certificates issued during a 10-year period in the State of Nevada in the United States for children under the age of six.” /2

We also conducted an experiment with 133 forensic pathologists in which we tested whether knowledge of irrelevant non-medical information that should have no bearing on fo- rensic pathologists’ decisions influenced their manner of death determinations. /3

The dataset of death certificates indicated that forensic pathologists were more likely to rule "homicide" rather than "accident" for deaths of Black children relative to White children. /4

“Participants read a vignette describing a not straightforward or simple case in which a 3.5-year-old child was presented to an ED with diminished vital signs and who died shortly after arrival. /5

In the vignette, the caretaker described finding the toddler unresponsive on the floor of a living room. Postmortem examination determined that the toddler had a skull fracture and subarachnoid hemorrhage of the brain. /6

By random assignment, each pathologist read one of two vi- gnettes, which were identical apart from two pieces of information: some were told that the child was African-American and that the care- taker was the mother's boyfriend /7

whereas the other pathologists were told that that child was White and that the caretaker was the child's grandmother. To be consistent with typical medical information, the race of the child was stated, but the race of the caretaker was not explicitly stated. /8

In the Black condition, pathologists were about 5 times more likely to rule the death as a "homicide" rather than an "accident" (35.4% vs. 6.2%), but in the White condition, the results were the opposite: /9

A dataset of death certificates in NV revealed that Black children, relative to White children, were more often judged as victims of homicides rather than accidents. /10

The experimental data, along with the death certificate data, taken together, show that even highly trained professional scientists can be biased in their decisions. /11

Thread for today. /0

It is fashionable for people to create sympathy to the unseen / unknown organisms. The poor things that can't stand up and fight for their own existence.

It makes for a brilliant narrative. It melts your hearts. And you get to play saviour of the oppressed by outraging. /1

But, for most part, such things are also false.

Amazon are the lungs of the world. Never mind that most of the world's oxygen production happens in open oceans. But these are harmless ones. Of course, we all love to maintain forests.

However, some things are sheer scare mongering.

For instance - take this: coral reefs will be permanently gone if mean / median temperatures raise by 1°C ..

But, really - how? Then you get a lecture on how CO2 will affect calcification.

Dig a bit deeper from another angle+

+ and you find that the earth was much much warmer during the age of Dinosaurs. So much so, that we had cold blooded lizards growing to sizes of buildings. Surely, there must have been tons of CO2 then!

And the ocean temps were quite high too.

The calamoid palms 🌴 have over 500 species spread across the world, but their higher-level relationships were a bit of a mystery. Until now.

Out today in #MolecularPhylogeneticsAndEvolution:

A robust phylogenomic framework for the calamoid palms https://t.co/JiCbSUlheH

1/10

First some background info, so that you know what we are talking about:

Calamoid palms look a bit like snakes 🐍 (don't they!?!), because their fruits are covered in overlapping scales. And with their often fierce spines, they are equally fearsome. 😱

2/10

They are classified into 17 genera, 10 subtribes and 3 tribes. They have an amazing variety of growth forms, from stemless to climbing to tree habit. 🌱🌴

3/10

But as I said, their relationships have been a bit of a mystery. Here's the varying relationships previous studies found over the last 20 years.

4/10

We tackled this mystery with a phylogenomic approach: we sampled almost a thousand genes (a hundred times more than previous studies!) of 75 species representing all calamoid tribes, subtribes and genera.

The resulting data matrix is pretty massive...

Fellow academics, when are we going to start fixing our urgent structural problems that strain family bonds and present ongoing barriers to diversifying our educational and scientific leadership? You wonder, what the heck is this guy talking about?
1/n

We’re all very familiar what I am talking about, actually: the impossibility for most academics in the life sciences to do their jobs in a reaonable amount of time, due to more and more demands on writing grants, and to a lesser degree, papers.
2/n

As of yesterday I hadn’t intended to write about this subject, but was wondering as I finished a Saturday of straight work, what happened to all my time? Why has WFH not reduced my pile of tasks to do? Instead why is my to-do list growing bigger and bigger?
3/n

I decided to figure out how much time our jobs actually require. I estimated per year (m=month, w=week, d=day, h=hour):
Teaching: 20h/w x 20w = 400h
Meetings of all sorts: 10h/w x 48w= 480h
Replying to email: 2h/d x 365d = 730h
Attending and giving talks: 2h/w x 50w = 100h
4/n

Papers: If each person needs 2 papers during a 5y stint, and you run a 7.5-person lab, then you need 7.5 papers per 2.5y = 3 papers/y. Throw in a review and it’s 4 papers. If you need 15d at 8h/d per paper, that’s 480h writing papers.
5/n

A relationship begins to get stiff when excessive patterns begin to form.

Too many patterns leads to a boring, predictable, logical lifestyle.

Get the emotions involved.

Do something spontaneous out of the blue moon & flip the script.

'What's wrong with the patterns?'

Nothing is wrong with patterns.

However, there is a problem when all you have are patterns.

It's boring.

'Can you explain why?'

Sure 👇

The thing with relationships is that it's meant to be an emotional experience.

It's very difficult to logically explain love, right?

'Right.'

Well this is where you want to steer the ship the right way.

1. Too emotional is bad.

2. Too logical is bad.

Let me break it down.

1. Too emotional

If a relationship is completely ruled by emotions, then it's too volatile.

You will never reach productivity if you are aimlessly only following each others emotions.

This lifestyle tarnishes any structure for the couple.

'So why do people do it?'

Because it's fun.

You may ruled by this stage in the honeymoon phase.

Normal.

You'll be so spontaneous that it almost becomes a lifestyle.

But it's hard to level up your life when you're too spontaneous.

Avoid.

You want to buy a house.

You take a loan from the bank.

The bank asks you, “what if you don’t pay back?”

You say, “take my home and sell it”.

(Thread)

That makes sense. The bank gives you a loan and in case you don’t pay, the bank will take over your house and sell it and recover its money.

That’s collateral.

Banks also lend money to big corporations. With them, banks don’t always have collateral.

So a loan where the bank has collateral is considered safer for the bank.

In the early 2000s, the banks in the USA were giving out loans to people for buying houses.

The economy had just recovered from the tech bubble in 2000 where many banks had given out loans to businesses that had shut down.

In that backdrop, the banks found giving home loans safer.

Moderna CEO Stephane Bancel was previously CEO of bioMerieux in France from 07-10.

Alain Merieux, who owns bioMerieux, was instrumental in the creation of the Wuhan Institute of Virology P4 Lab.

The same people who helped create the virus, also helped to create the vaccines...

Moderna partnered with French Pasteur Institute in 2015 to develop mRNA vaccine technology.

Pasteur Institute partnered with the Wuhan P4 Laboratory in 2017 along with the Merieux Foundation to study emerging viruses...

Nobel prize winning scientist Luc Montagnier asserts that Sars-Cov-2 is man-made and originated from the Wuhan Institute of Virology.

Montagnier did extensive work with the Pasteur Institute in France which was partnered with the Wuhan P4.

Merieux Foundation & the Chinese government have worked together since 1965, and partnered to study emerging pathogens in Africa in 2015.

Their research included "PATHOGENS CARRIED BY BATS" that provoke respiratory diseases.

1/ I am seeing more and more founder secondary in venture rounds (Secondary = founders selling some of their shares before some other shareholders are able). Series B-D. I see both as an investor and through entrepreneur circles.

2/ I like secondary for entrepreneurs. Moderation is key but in a lot of situations I think it helps accelerate the co. Lots of very smart investors disagree. Here are my thoughts.

3/ Magnitude: My basic rule of thumb from what I see is market is 4+ yrs and up to 10% of founder’s equity stake with some $ cap that makes sense given stage etc. (typically <$10m)

4/ The entrepreneurial journey is brutally hard. Giving some financial relief helps remove one piece of pressure. I don’t think that secondary in the magnitude mentioned impacts the drive/persistence of great entrepreneurs.

5/ That secondary means they will be able to just sleep knowing they can pay their kids’ tuition. Secondary will make most founders better at their jobs, thus accelerating the co.
