Your entire comment ignores how humidity plays a role, which is rampant in houses when you bring snow in from outside, or as soon as you open up any door to go in or out, the air rushes inside causing a moisture spike for up to hours at a time.

It’s not JUST temp. You can have condensation at 20c with a high RH, or you won’t have any if you can manage to keep the RH at a manageable level and prevent pockets. Which is another reason why airflow is important, there’s multiple like mold prevention, dust, mildew, pollen, hair, dander, etc. you NEED airflow. And that’s done by utilizing the physics of the difference between hot and cold and the drafts it creates. Especially when you don’t have forced air central conditioning/heating.

Airflow is the only thing that mitigates it. If you have a glass of water, it can have condensation on it, but place it a flow of air (like a fan) it will evaporate and leave the glass feeling dry. Thats how you prevent/remove condensation. Heating the room, only changes the RH so much.

You must live in a fair weather place and have never experienced cold weather have you?

Will research even change your mind? there’s hundreds of studies that have been done about how crucial airflow is to basic air condition. This study even pulls research from 1965, so it isn’t like this is something new either….
