Opportunity of a lifetime?

Whilst we experience what will hopefully be a once in a lifetime pandemic, there is also a once in a lifetime opportunity.

For those of us who are fascinated by consumer purchase behaviour, right now we have a rare insight into crisis stimulated behavioural change. Have you noticed a surge in customers switching brands due to specified marketing influences? For example, Dettol cleaning products specifically mention that they kill Coronavirus, among other things.

Or are customers more comfortable with the brand they bought a couple of months ago because it is tried and tested? Have you noticed customers switching to well-known reputable brands from store branded items? Are certain brands deemed as more trustworthy in times of crisis?

We all know that correlation does not imply causation, but in this case can we make that inference?
