No.
Not any more so than I have to ask the guy who invented a football if he intended it to be used as a tea strainer.

Can we cut it out with the trolling claims already?

Kyripid I'm not the only one on this thread that notices that the chemist acts like a troll, he adds nothing to the discussion and repeatedly posted comments that are intended to add disinformation or to attack the person he is replying to, take his recent apology for lying, to paraphrase it was "I dumped down my reply for you stupid people"

Quote from: Bored chemist on 19/02/2021 08:43:04
I guess I should apologise for trying to simplify the situation to a point where you can understand it.

He is inherently trolling, and while he does I will call him out on it. Others choose just to ignore him. Clear the chemist is more interested in provocation then discussion.

Quote from: Jolly2 on 20/02/2021 17:38:13
you have to go with the evidence

Okay, so where's the evidence?

Quote from: Jolly2 on 20/02/2021 17:38:13
the evidence for a lab release has increased.

How do you figure? The video you posted doesn't give us such evidence. If you disagree, then tell me the relevant timestamp, because I must have missed it.

They discuss supporting evidence for a lab release in a few places,

40.50

At the start of the discussion Bret cites it's clear adaptability to infect humans as evidence that points to a lab release. 19.15 on

Quote from: Kryptid on 21/02/2021 00:32:19
Quote from: Jolly2 on 20/02/2021 17:38:13
Whereas the evidence for a natural zoological origin has been diminishing

Has it? Again, your video doesn't support that.

They have no intermediary any more they are left looking at feret badgers while there is no evidence it came from feret badgers. Hence all past suggestions for a zoological origin are now dead ends, there were more hypothesis before now there are less, hence diminishing.

We have no evidence for any intermediary currently,  and scientists that have investigated pangalins as one possible intermediary now excpet it couldn't be.

Quote from: Jolly2 on 19/02/2021 03:12:38
It's funny you suggest a conclusion Kryptid  he never gave one

He has stated that he is 90% certain of the lab leak theory, so it sure sounds like he's come to a conclusion to me.

Where is that time stamp? You either believe that mistakenly or are being dishonest. I never once recall him ever suggesting 90% certainly of a laboratory release.

With the secound data set.

Weekly incubation period and an R.0 of 3.

Past infections .  current infections

Patient 0
Week 1.  1              ,   3
Week 2   3              ,   9
Week 3   9              ,  27
Week 4   27            ,  81
Week 5   81            ,  243
Week 6 243            ,  729
Week 7  729           , 2,187
Week 8 2,187         , 6,561
Week 9 6,561         , 19,683
Week 10 19,683     , 59,049
Week 11 59,049     , 177,147
Week 12 177,147   , 531,441
Week 13 531,441   , 1,594,323
Week 14 1,594,323 , 4,782,969

After one month from patient 0

You have between 30 to 80 people infected. With patient 0 in mid September.

The Wuhan games are at this time

 Wuhan 2019, was held from October 18–27, 2019 in Wuhan, Hubei, China.

There were just under 10,000 athletes taking part in the games.
That's not including people that watched them, or officials involved in referring the games.

I cant find actual numbers for total people present but we could easily assume a few thousand more, watching and refereeing.

There are claims by many athletes that they got sick during the games.

With an R0 3 and a week incubation period. Those infected at the games would then each travel to their home countries afterwards.

There is this story about French soldiers returning sick from wuhan.
https://www.mirror.co.uk/news/uk-news/french-army-returned-wuhan-military-21988912

https://www.dailymail.co.uk/news/article-8291755/Did-European-athletes-catch-coronavirus-competing-World-Military-Games-Wuhan-OCTOBER.html

The second data set certianly matches with the wuhan games as the source.


We see 20,000 deaths world wide at the begining of March 2019. To hit that figure you need atleast 2 to 3 million infected.

Under the ratios with a weekly doubling and R03 we get the end of mid November, As the source for patient 0.

Yet we know 3 R0 is on the high end the R0 is between 1.4 and 3.

The difference between the two translates to the pandemic taking more time to get to 2 to 3 million infected.

At and Ro of 1.4 and a weekly doubling

Week 1.  1              ,   2
Week 2   2              ,   4
Week 3   4              ,   8
Week 4   8              ,  12
Week 5   12            ,  17
Week 6   17            ,  24
Week 7   24            ,  34
Week 8  34             , 47
Week 9  47             , 65
Week 10 65            , 91
Week 11 91            , 127
Week 12 127          , 178
Week 13 178          , 248
Week 14 248          , 348
Week 15 348          , 485
Week 16 485          , 681


Takes 4 months to get 681

I didn't lie.
I did simplify things.
If you want to describe yourself as stupid, I'm not going to stop you.

Now, back to the point:
Do you think that you need to ask the designer of a football, if he intended it to be used as a tea strainer, or can you tell from the fact that it simply wouldn't work that he did not have that intention?

That's like interpreting a shooting murder investigation eliminating human suspects as "diminishing evidence that the murderer was human". Do you have any idea just how many animals there are? Do you really think we've come anywhere remotely close to testing them all?

There is no time stamp because he didn't state it in that video (nor did I ever claim that he stated it in the video). Where he stated it was in an interview with Bill Maher: https://www.thedailybeast.com/bill-maher-pushes-bonkers-steve-bannon-wuhan-lab-covid-conspiracy

Quote from: Jolly2 on 22/02/2021 16:47:18
You either believe that mistakenly or are being dishonest.

Really? In the interview with Bill Maher, he said, "Oh, it’s far more likely than that,” replied Weinstein, adding that “it looked to be about 90 percent” probability that it originated in a lab. How is that me being either mistaken or dishonest?

Oh my you actually read any of his posts? He has been suggesting an R0 of 7, defended ideas related to a mortality of 4%, claimed that covid evolved in bats, which is a total lie then apologises for lying by effectively saying he was dumping down his reply for us stupid people.

He reaptedaly seeks to twist what people say and as petrochemicals stated antagoniese people.  To not see his trolling is willful blindness.

Ask Bret if actually watched the video. You know as much as me.

They actually state a few example in the 9 minute video at the bottom of this reply.

Covid is adapted to indoor transmission not transmission outside, you would not expect that in a natural virus,  it is adapted to infect many different types of human cells.
The cleavage site that isnt found in Any other Corona virus. Its adaptation to be transmissive inhumans more then in Bats, or other animals.

You should have referenced the actual interview as your evidence in the first place,  by not doing so I was left believing you were talking about the video we were discussing originally.

Here is the actual discussion 9 mins

He says "I believe back in June I said the chances of covid comming from a lab looked to me to be about 90%"

he has been suggesting an R0 of 7

I haven't researched it, so I don't know if that's true or not. It's no doubt a variable number, though. EDIT: Having done some research, I found a reported R0 value of 5.7: https://www.healthline.com/health/r-nought-reproduction-number#covid-19-r-0

Quote
The R0 for COVID-19 is a median of 5.7, according to a study published online in Emerging Infectious Diseases. That’s about double an earlier R0 estimate of 2.2 to 2.7

Quote from: Jolly2 on 23/02/2021 00:37:47
defended ideas related to a mortality of 4%

The death rate has varied over time and from one place to another. The statistics show a case fatality rate range of less than 1% to above 14%: https://ourworldindata.org/mortality-risk-covid The case fatality rate worldwide does seem to be below 4% at the present moment, though.

Quote from: Jolly2 on 23/02/2021 00:37:47

How do you know?

Yes diminishing suspects absolutely.

And is it at all sensible to seriously consider that an alien or ghost or some other non-human entity shot someone simply because the police have eliminated several possible human suspects?

And all of those individuals have been checked?

Oh my you actually read any of his posts? He has been suggesting an R0 of 7
It wasn't me that suggested it.
It was a research group in China, using the early data in Wuhan.

And everyone on the thread agreed that the right value of R0 to use was the one based on the early data in Wuhan.

defended ideas related to a mortality of 4%,
From worldometer,
UK deaths   120,757
UK recovered  2,548,621
So total resolved cases 2,669,378
100* 120757/2,669,378 =4.5
That's 4.5%

So, yes.
I'm defending the right answer.

claimed that covid evolved in bats,
For the most part, it did, didn't it?

It's hypothesised, but not proven, that there was at least one intermediate species.
But the point I was making with that simplification was that it happened in the wild animal population, not in a lab.

How could I do that?
Are you claiming that your message is so unclear that I can always show that it means the opposite of what  you thought it did?
Isn't it more likely that I can show that you are wrong, simply because you are wrong?

Quote from: Jolly2 on 23/02/2021 00:37:47
To not see his trolling is willful blindness.
Pointing out that you are wrong is not trolling.
You continuing to post nonsense is trolling.

He says "I believe back in June I said the chances of covid comming from a lab looked to me to be about 90%"

Quote from: Jolly2 on 20/02/2021 17:38:13
Well rather then stating an opinion you have to go with the evidence and as Bret Weinstein stated in the video you clearly still have not watched,
Why do you think we should listen to Bret's opinion?
He hasn't supported it with evidence.
That number- 90%- is one he just made up.
A made up number is not science, though it will fool some people into thinking it is.

The R0 for COVID-19 is a median of 5.7, according to a study published online in Emerging Infectious Diseases. That’s about double an earlier R0 estimate of 2.2 to 2.7

defended ideas related to a mortality of 4%

The death rate has varied over time and from one place to another. The statistics show a case fatality rate range of less than 1% to above 14%: https://ourworldindata.org/mortality-risk-covid The case fatality rate worldwide does seem to be below 4% at the present moment, though.

Which drops even lower after you account for unrecorded cases. The data is all based on recorded deaths and recorded cases or positive test results and there are millions unrecorded and untested.

Hence the suggestion of 4% isnt appropriate with the data we have and its even less appropriate with the unrecorded cases. 80% mild symptoms or asymptomatic many have had covid and not even realised.

That covid evolved in bats which is a total lie

How do you know?

Well as Bret points out covid 19 isn't adapted to transmission in Bats, Firstly, secondly they are not even sure the similar virus found in Bats is the original virus covid came from. Looking at the virus structure and evolution,  they are certain the intermediary was a critter, not a bat. Mink seems to be an animal that covid is adapted to infect, ferrets also.

Once he starts trolling he generally doesn't stop, ofcourse only those trolled notice it first.  I'll follow your advice and the decision of petrochemical and just ignore him.

I did watch the video. I'm not going to ask Bret when you are the one here supporting his views. If you are promoting his arguments, it's up to you to defend them.

Ok, not sure I was defending his views rather I was adding them to the discussion. I would happily critic him also if he said something I didn't agree with.

Yes diminishing suspects absolutely.

And is it at all sensible to seriously consider that an alien or ghost or some other non-human entity shot someone simply because the police have eliminated several possible human suspects?

You missed the gist of my argument,  there is a murder and the owners pet knows how to fire a gun, because the owner thought it was a funny party trick.

Point being the police are unlikely to think the cat or dog shot the person,  on discovering the dog or cat can fire a gun, they would ofcourse become an unlikely suspect, and the main suspect should all the other suspects be eliminated by an investigation.

Not an arguement only some animals can have been the intermediary,  not all.

And all of those individuals have been checked?

Why would they? The evidence of the viruses evolution points to critters,  you could test a dolphin but when covid wont infect or be transmitted by them its kinda pointless.

You should have referenced the link as your evidence in the first place,  by not doing so I was left believing you were talking about the video we were discussing originally.

I'll accept that as my fault. I should have posted the link.

All good.

No. They do not.
They cite that range for the virus TODAY.
But not for its growth in the city of Wuhan before it was known that there was an outbreak.
And that is the value that you need to use to model how the disease would spread in a naïve population.
And that was the issue under discussion at the time.

So there's no question about the current value being something like 1.4 to 2.5.
But that's not relevant.

The trouble is that Jolly can't accept any sensible value for R0 in the early stages of the outbreak of covid, because it makes it clear that his suggestion that it might not have started in Wuhan is even more absurd.

Because unrecorded cases are unrecorded,  there is no way to know what their effect is.

You can't allow for something that you can't measure. That's just wishful thinking, not data.

However, I was able to provide real numbers to show that about 5%
You have not been able to provide any data to show that you are right.
So, once again, showing that you are flat out wrong, is not trolling.

Just going to add a point you missed.

The only reason I was looking at the R0 incubation period and morality rate. Was in an attempt to use the data. To find when patient 0 was.

I did the data for an R0 7 with a mortality rate of 4% with an incubation period of 4 days.

With 20,000 deaths world wide at the beginning of March 2019. Patent 0 would have been in February 2019 an entire month after China already declared an outbreak.

Hence those number are rediculas.

An R0 3 with an incubation period of a week puts patient 0 in arround the begining of November maybe late October.
