Also, scientists stand apart from their subject matter--as distantly as possible. Physicians, on the contrary, are in "a relationship" with patients. 2/
Sorry, Dr. Jha, but you shouldn't confuse medical care with the scientific enterprise. Although the 2 are commonly conflated, they are really distinct. 1/
The hearings are meant as a questioning of the scientific process

To sew doubt on what we know and how we know it
So a group of us organized a response, which we just posted on our website
It isn't pro or anti hydroxy
Its about the scientific method and why it matters

First, scientific knowledge is often limited or provisional, especially with a new disease.
Second, for every patient there are myriad circumstances that influence a medical decision. /3
Fourth--and most pertinent here--one cannot narrowly limit the scientific knowledge to only RCTs as you do in your statement. /4
I won't rehash all the arguments here (and there are many!) but I'm sure you're familiar with this piece by Dr. Frieden from only a couple of years ago https://t.co/f7jHvDujUZ /5
My point is that your attacks miss the point: Medical standards cannot be reduced to scientific ones. /12
If you have an interest in the historical background for this, here are a couple of the pieces that I wrote on this topic a few years ago: /14

I took a look at Shell's first ever 1.5C scenario and found that it is... remarkably similar to its “well-below 2C” scenario.
Oil, gas, coal, solar.... all basically unchanged.
The key difference: A new forest the size of Brazil to suck up the extra CO2.
Including "nature-based solutions" in the outlook brings forward the date for net-zero emissions to 2058.
Without them their pathway for CO2 emissions is the same as the previous one.
(It's also towards the higher end of 1.5C emissions pathways.)
The "Brazil-sized" forest idea isn't actually new, it has been kicking around for a couple of years.
It was referenced in the "well-below 2C" scenario although not formally included in it, and Shell's CEO has been framing it as the only viable way of getting to 1.5C.
Fine, but who is going to plant all those trees? Well... Shell says it will plant some of them.
Only yesterday Shell said forests were a key part of its net-zero strategy.
Not everyone is convinced though

Given that Shell's 1.5C scenario also sees a big scaling up of bioenergy, the question remains: where are all those trees and bioenergy crops going to go?

Shell plans to use forests to remove 120 Mt/yr of CO2 by 2030.

Appropriate land for forestation is finite, and risks competition with food production and human rights of current land owners/users, esp Indigenous
