Nigel Evans Excerpts

Tuesday 30th November 2021 Commons Chamber

[Mr Deputy Speaker (Mr Nigel Evans)]

Order. Important though this matter is, the hon. Lady does appear to be straying. Could she please get back to the regulations that we are discussing?

[Daisy Cooper]

The point that I am trying to make is that the Government are framing the introduction of these specific restrictions in terms of whether or not there is extra transmissibility from the new variant. My concern is that they are not talking about whether we need these restrictions, and perhaps others in the future, because of the pressures on the NHS in its broadest sense.

[Mr Deputy Speaker (Mr Nigel Evans)]

I see five people standing; the debate has to finish at 3.58 pm and we all want to give the Minister sufficient time to be able to respond to the number of important questions asked during the debate, so will people be mindful of the length of their contribution?

The hon. Gentleman makes the point most eloquently. Politicians then become fearful. They think, “What if the worst-case scenario is right?”, and lose faith in more balanced predictions.

John Ioannides from Stanford University said of Ferguson’s modelling that

“major assumptions and estimates that are built in the calculations seem to be substantially inflated”.

He is a serious customer, Professor Ferguson, and Imperial has an impeccable reputation. I pay respect, overall, to their work, and I do not seek to criticise for the sake of it; I want to highlight that bad forecasting and bad modelling drives bad Government decisions that then become illiberal and intolerant of other people who have more balanced views.

More recently, in July 2021, Ferguson predicted 100,000 cases, saying that it was “almost inevitable”. Yet we got nowhere near there. The US forecaster Nate Silver, who is very good at predicting US elections, said:

“I don’t care that the prediction is wrong, I’m sure this stuff is hard to predict. It’s that he’s consistently so overconfident.”



The political scientist Professor Philip Tetlock agreed with Nate Silver, adding:

“Expect even top forecasters to make lots of mistakes…When smart forecasters are consistently over-confident, start suspecting”

other factors in play, such as

“publicity or policy-advocacy games”.

I make no such allegations.

More recently, I understand that this summer Professor Ferguson predicted upwards of 100,000 cases. They topped at just over 30,000. In an interview with The Times, the good professor said that his prediction was off because the football messed up his modelling. That for me comes to the essence of the problem with forecasting. When someone can predict 100 million deaths and no one dies but someone gets a sore thumb, they can say mitigations were taken by Government. When a forecaster’s work becomes verifiable, we can see when he predicts and gets it wrong. When that forecast comes up against reality, reality kicks in and makes a fool of the forecast and sometimes, sadly, a fool of the forecaster. Every time Professor Ferguson’s forecasts have been verifiable, they have been seen to be very badly flawed, and this is a serious man and a serious university.

To sum up, if we look at the forecasts made about covid, just like the forecasts for so many other things, reality changes those forecasts and very often undermines their credibility, so we need another set of factors to guide us. Members on the Opposition Benches and on this side have said we need principles. We need a precautionary principle, but we need a sense of balance so that we do not overstep the mark, damage our society, damage our young people and damage poorer people by seeking to control when we need to learn to live with this. My final question to the Minister is: will the Government look into forecasting and perhaps hold an inquiry into the success of forecasting and what we can learn from it, so that we do it less badly in future?

Finally, going from the theoretical to the very practicable, and on a point related to the Isle of Wight, we are not getting the boosters in the Riverside Centre. My hon. Friend the Member for Winchester (Steve Brine) raised a specific point about his constituency, and in the same way, will the Minister please look at getting more booster jabs to the Isle of Wight and our Riverside Centre?

[Mr Deputy Speaker (Mr Nigel Evans)]

The last contribution before the Minister responds is from Dr Andrew Murrison.
