Second, it would not have been possible to use an experimental design, so all our findings are correlative, and we cannot put forward causal relationships. Shortly before the lockdown, people might have chosen to move away from their families because they work in health care and did not want to infect their family members. People that lived on their own before the pandemic might have agreed to isolate with others to combat their loneliness or to help with care work in the family. Those examples are likely rare and might only mildly affect our findings. Even though we were not able to control for confounding variables, some pre‐existing factors, such as age and gender, may at least indicate a direction of effect.
