Back when I was 16 (this was in 1972), I was playing in a band that had just hooked up with a new lead singer. During one band practice, he asked me whether I had ever heard of "Scientology." I said that I hadn't. He asked whether he could arrange to send me some literature on the organization and I said "sure." A few weeks later I received a brochure from Scientology. It claimed that the organization was scientific. I remember the literature containing photos of people being tested or trained using electronic meters with electrodes that were attached to their skin. I didn't know what to think of all of this at the time, but I didn't respond to the brochure's invitation to call a phone number to learn more.
A week later, I received another piece of literature, and then another and another. Sometimes these were postcards, sometimes booklets. Sometimes they described various aspects of the organization. Sometimes they invited me to lectures, open houses and other events. I began to think of Scientologists as being a bit over the top; somehow, they reminded me of UFO believers (I don't actually like that term; I'm referring to the people who believe that sentient beings from other planets have visited Earth).
The Scientology literature kept streaming in, week after week. Sometimes I received 4 or 5 pieces of mail in a week. I almost always received at least 3 mailings every week. I was living at my parents' house in Overland Missouri at that time, and I would glance at this stuff and throw it away. But it kept coming, month after month and then year after year. I never responded to any of this literature. I never made a phone call to anyone at Scientology and no one from Scientology ever called me. I did go to one open house at the St. Louis Scientology center, but I merely looked around for less than an hour, then left. I never signed anything or asked to stay on the mailing list.
I moved away from home in 1978 to go to law school. The mailings continued to come, though, at least two per week. Even after I graduated from law school (three years later) the literature was still coming, at least one per week. To the best of my recollection, an occasional piece of Scientology literature was still being sent to my former house in Overland, even as I approached 30 years of age.
This will be a wild guess, but I would bet that I received an average of 2 pieces of mail per week from Scientology from 1972 until 1985. that would mean that I received well over 1,000 pieces of mail from Scientology, even though I never responded.
When I visited home and saw the piles of stuff waiting for me on the mail table, I felt sorry for the members of Scientology who were paying to send me all of that mail. I assumed (based on stories I read) that many young adults were handing over almost all of the disposable income to Scientology so that the organization could send me mail that I would throw away.
Like many things I've experienced, there is no lesson I can draw from this experience, merely this anecdote regarding the endless mailings I received from Scientology.
