Would you agree that the present perfect is used more than the past tense by native speakers to emphasize the situation at hand?
They use the tense that emphasises the situation at hand, to emphasise the situation at hand? Yes, they probably do. This is tautologous.
If you want to point out that something happened, and if that thing happens to have a lasting effect, then you have a choice between the simple past, and the present perfect (and perhaps the present continuous, depending on the facts of the matter). Most often the simple past will be chosen.
If you want to point out that something happened, and include that it has a lasting effect in your statement, you can either use the present perfect, or use the simple past and then make a second statement to the fact that it is still in effect. This latter choice would be rather clumsy in English.
I found my pen. I still have it.

I have found my pen.
I have read the leaflet you gave me.
I do not think I need to be enchanted, to favour the latter two in these cases.
In other cases where we've a freer choice between simple past and present perfect (because it has an impact on the present, but we either don't care or can let that be assumed), we tend to use the simple past.
