The bolded is an interesting theory. It would in its basis be supported by Canada being exhibit A of anonymous society, particularly in cities, and in being a society not defined by one subset of mores, values, rules expectations. In other words we are a make it up as we go along hodge podge. Anything goes tends to be more replete in that environment. But other variables exist as well. Dutch probably veer more to extroversion, confidence, interaction, and a sense that the joi de vivre is the seeing of other people, continually, and always.
Canada in contrast being one of the most sparsely populated per land mass regions on Earth is probably more given to introversion. That we are very multicultural factors into that as well. These are interesting (I think) contrasts in respect of behaviors and a pandemic. We see within Canada that Quebec behavior and results looks generally much different than other provinces. Quebec too would probably select more for extroversion, people interaction, hugging, kissing.
But yeah, its much easier to lie in anonymous introverted society where people don't know each other. But easier to distance in that society as well.
Finally the amount of people describing "friends" as people online would be higher here than say in most places in Europe where first person contact remains the preferred mode, and friendship mode. Maybe our distance here makes us more susceptible to distance contacts. even within a sprawling city like Edmonton harder to meet in person. In Amsterdam one can bike fairly easily to 80% of the population one knows of.
