What do we call someone who does not like to gossip?

What is the one-word description of someone who avoids gossips(listening and spreading as well)? Specifically, not a recluse, but a sincere and practical person who believes in realistic-facts and not dramatic, sensational but trivial stories.

Solution 1:

There are several candidates. Here are four:

Reserved = Reserved people do not often talk about or show their feelings or thoughts:

Cambridge

Reserved = restrained in words and actions

Merriam Webster

Reticent = unwilling to speak about your thoughts or feelings

Cambridge

Taciturn = tending not to speak much:

Cambridge

Restrained = acting in a calm and controlled way

Cambridge

Of these, I would normally use reserved because it seems to include the qualities of the other three. A reserved person may be taciturn, restrained, reticent, or any combination of the three.

Solution 2:

who believes in realistic-facts and not dramatic, sensational but trivial stories

grounded might fit here:

—used to describe a person who is sensible and has a good understanding of what is really important in life (Merriam-Webster)
