The 'Blitz spirit' in reality and in ideology - four comments
1/5
2/5
Yes, adversity (including coming under attack in war) can bring people together in solidarity - if they also have the capacity/ resources to provide that support.

See our new chapter on collective resilience in wars:

3/5
Charles Fritz's observations of the 'Blitz spirit' in London were the inspiration for his important work on 'therapeutic communities' in disasters:

(This is one of my favourite papers in the disasters literature)

Vaccine passports and possible unintended consequences - a short thread of (*open access*) research evidence.
1/9
2/9
This new correlational study by Porat et al. found that that the more people felt they themselves had control & the authorities understood their needs, the more willing they were to get vaccinated and their actual vaccine status.

mdpi.com/2076-393X/9/8/…
3/9
If vaccine passports were perceived to frustrate these needs (for autonomy and relatedness), therefore, we'd expect passports to de-motivate people from getting vaccinated.

The question I am asked most by journalists at the moment is how the public will behave after so-called ‘freedom day’.

A short thread.
1/9
It’s difficult to predict as there are multiple interacting factors.

First, the change in policy sends a very strong signal (to some people) that the pandemic is less serious
royalsocietypublishing.org/doi/10.1098/rs…
2/9
In addition, the telegraphing of ‘freedom day’, as last year, has an effect in reducing adherence in the weeks leading up

The mini #Hajj 2021 begins today - only 60,000 (Saudi based) pilgrims instead of the normal global gathering. Here's a thread of papers by @HaniNabulsi which examine the crowd psychology of the Hajj in normal times.
1/4
The negative effect of crowd density on reported safety was moderated by social identification with the crowd. Mediation analysis suggested that a reason for these moderation effects was the perception that other crowd members were supportive.

2/4
Shared social identity with the crowd explained more of the variance in cooperation than both location & density. The link between shared social identity & giving support was stronger in the plaza than in the Mosque, with @DrAnneTempleton

Tory MPs fear public fear: The MPs consider their own fear rational but that of the public irrational.

In fact there is a long history of elite fear of public panic...
independent.co.uk/news/uk/politi…
2/4
The policy of not telling the public the facts about threats in case they panic has been a feature of guidance documents on emergency preparedness
tandfonline.com/doi/full/10.10…
3/4
But lack of information in an emergency actually creates anxiety. In trying to protect the public from fear, the authorities damage trust. In an emergency, people need practical information not emotional reassurance ('stay calm', 'don't panic')
