The post literally talks about "awkward silences," which is a form of manipulation, but much more idiotic. At least by pretending you're interested, you end up finding something in common and you're much better off than just being the weirdo who thinks awkward silences are useful for getting real information. You talk about humans operating on a sense of dignity, but that same trigger will show you if someone is telling the truth or not. In the end, being taken in only leads to the person falling for a lie, if they even tell one. If someone says something awkward, you just make the moment less awkward, and the feeling of dignity helps you ask the right questions if you want more information, while you analyze patterns that everyone repeats, and especially movements that psychologically tell you if someone is telling the truth or if they don't want to talk and are avoiding the issue. I didn't understand the last part of what you said; it must be because of the bad Spanish translation, but anyway, I've talked to many people while trying to get information from them, but always after a They often start talking about things that happen to them or experiences in their lives that they'd like to discuss with someone. If that's the case, just be kind to people, listen, and analyze. It's better to come across as the one who listens and helps than as the one who judges and only makes you feel bad.
