Effect of “Share your thoughts” on you?

What effect does “Share your thoughts/experience/do you agree” in a video/post have on you?

Web search shows this call to action as one of the basic methods to drive engagement, but articles I checked didn’t include the psychological reasoning behind it.

  1. Does it encourage you to engage? Would you do it if the action was not there?
  2. Do you consider it an indication the author is interested in you?
  3. Or the decision to engage is driven by your perception of the author and your interest on the topic? In which case the task doesn’t have any effect.
  4. Is it overused phrase similar to “Like and Subscribe” on monetised Youtube videos?

My opinion earlier sided with 4. as that’s where I consumed most content. But I also don’t engage there, so it didn’t matter if it was present or not. Though I enjoy reading comments - and I somehow have perception, not validated, that then the ask does lead to more engagement.

If you use it in your posts - what effect did you observe? Keen to find out.
