It can work yeah. From experience it’s usually more catching people out and about while you have the pamphlet bag and they get curious. Otherwise you’re just leaving pamphlets in doors. Calling people seems to be worse in my experience. If you catch someone outside there’s a good chance you aren’t interrupting with a short conversation. Whereas phone canvassing has gotten worse and worse about that somehow. Maybe it’s just something psychological. Some of my best results were being in the same area twice, (to finish pamphletting doors), and someone who couldn’t talk the day before can talk the next day and they give you time because you didn’t chase them like a salesperson.
