I was more reassured by the strategy overall.
Use the interventions that make the biggest impact at the right times to reduce the peak sounds sensible.
However, behavioural science isn’t actually science - it’s a social science and far less precise. People are complicated.
Key gaps from speeches and questions:
Will people actually do this (eg the 7 day quarantine)?
How will they know/track this?
What level of compliance have they assumed in their modelling? What will they do if there isn’t the level of compliance expected, given we are depending pretty heavily on these few key effective messages over a matter of weeks?
Has this type of intervention (asking people to stay at home 7days) actually been tested in real life vs on a spreadsheet?
Have they considered barriers to doing this for all types of people across the population in their assumptions? Eg financial, language, etc ie not everyone is a middle class Londoner but are they just assuming everyone has their outlook and cushioning?
