The Government’s Latest Scary Modelling is Already Wrong

There follows a guest post by Daily Sceptic reader Graham Williams (a pseudonym), a maths graduate and by profession an analyser of business plans, models, forecasts and funding requests. He is not impressed with the latest Government pandemic modelling.

I have just read the SPI-M consensus statement paper of September 8th, which appears to be at the heart of the recent stories about possible future lockdowns etc. This paper seems to be as big a load of negative, hyperbolic scaremongering as all the ones they have issued so far this year (February at the start of the roadmap, March, April, June and July).

In paragraph two they state: “SPI-M-O groups have reflected on their modelling of Step 4 of the Roadmap, and despite unexpected falls in cases in mid-July 2021, these scenarios can still be used to consider the future autumn and winter trajectory.”

They appear however not to have reflected that were it not for the unforecast Delta variant their modelling since February would have overstated the position of deaths, cases, and hospitalisations by June 21st by around 1,000%. Even with the rise caused by the variant, their forecasts remained hugely overblown, but they still continue to model with the same flawed methodology.

After paragraph two there follow about 18 paragraphs of largely unsubstantiated waffle with a few facts thrown in.

One of the facts is that R is currently (i.e., at the date of the paper) between 0.9 and 1.1, so broadly flat. The covering page to the report says: “These are not forecasts or predictions… They are based only on the observable trends and data available at the time the projections were produced.”

Had the modelling actually done what it said on the tin, project observable trends, then it would have been in line with their own medium-term projection of September 8th, which shows a fairly flat trend for September, even if arguably the base they have used is a bit low.

SAGE Modelling From May Last Year Said Approach Recommended in Great Barrington Declaration Was Least Bad Alternative to Lockdown

We’re publishing an original piece today by Lockdown Sceptics regular Glen Bishop, a second year maths student at Nottingham University. Glen has read a paper released by the Warwick modelling team that is part of SAGE’s SPI-M group last May and uncovered some interesting facts. Not the least of these is that when the team modelled what the signatories of the Great Barrington Declaration refer to as “Focused Protection”, i.e. protecting the elderly and allowing those who aren’t vulnerable to the disease to go about their lives taking sensible precautions, as they would during a normal flu season, the projected loss of life between March 2020 and May 2021 was 138,000, only 11,000 more than the 127,000 that have supposedly died from Covid already, with the Government embracing the suppression strategy endorsed by SPI-M. The modelling team also acknowledges that of all the alternatives to an indiscriminate lockdown, shielding those aged 60 and over would have resulted in the least loss of life as well as the least socio-economic disruption. Here’s the key paragraph from the Warwick paper:

A completely uncontrolled outbreak is predicted to lead to around 200,000 deaths, approximately 2 million QALY losses but no lockdown impacts. If the current controls are maintained until the end of 2020, then we predict 39,000 deaths this year [2020], but a further 159,000 if controls were then completely removed. Regional switching and age-dependent strategies provide alternative exit strategies in the absence of pharmaceutical interventions. Of these, the age-dependent shielding of those age 60 or over generates the lowest mortality and also the lowest lockdown scale, thereby minimising socio-economic disruption. However, it is unclear if a protracted lockdown of this age-group would be practical, ethical or politically acceptable.

Glen’s article is worth reading in full.
