Venezuelans didn't leave because they were "biased", good grief. They left because they were suffering under poverty, hyperinflation and violence.

There’s still a selection bias involved, just as there is with Cubans in Florida.

Those that leave are mainly the ones with means and/or the ones who feel strongest about it.

The set of people that left their country is not random, and certainly statistically biased.

That's not what they said. They said people who left are inherently biased, because they had to leave, which makes perfect sense.
