I once thought it was as simple as "you gotta' believe". Believe in the Force and in yourself. Han is too cynical to buy into a bunch of "simple tricks and nonsense".
I can say that I once thought this as well. However, I found myself at a loss when Leia heard Luke call to her in ESB.
She wasn't trying to hear Luke. After all, she didn't know he would call to her. So there's no "you gotta believe for it to work" moment there and yet she still hears him.
This was cemented in ROTJ when Leia said the following:
"Luke, you have a power I don't understand and could never have."
That doesn't sound like a believer.
Trust me, I'm not midichlorian apologist. I've just found myself wonering over the years since TPM if there may be some happy medium between the mystery and the science.
Maybe it was the terrible way it was explained, the obvious forced exposition. But I can honestly say that when Qui-Gon took a sample of Anakin's blood for Obi-Wan to test his "midichlorian count", I didn't find myself saying whaaaaat?
That didn't come until the Jedi Temple and landing platform scenes.
