The three-tier approach to local lockdown restrictions in England (see paragraph 117) introduced more complexity to Government messaging which was, understandably different in different parts of the country.231 It was therefore unsurprising that this more differentiated messaging strategy meant that levels of public understanding and compliance began to deteriorate. Written evidence submitted by UCL showed much poorer comprehension of the rules than at the beginning of the pandemic. By October, fewer than half of the over 70,000 adults who took part in the survey reported broad understanding of the rules (45%), with just 14% understanding them ‘very much’. Self- reported compliance was consequently also much lower, with just over 40% reporting ‘complete compliance’ with guidelines, compared to 70% earlier in the pandemic.232
