Since the video of the guy talking about dog toys with chrome closed, and then seeing dog toy ads shortly after, I've become skeptical of this. So, I've begun testing it myself. I thought of something somewhat specific but random, unrelated to me, unlikely for me to see regular ads for, and now from time to time I talk about that thing. Until maybe a few weeks from now when I stop doing this, I will not be typing the thing, or anything too closely related, into any kind of text field. I've been doing it a few days so far and nothing yet.
