First of all, sorry if this is a duplicated question... But I haven't found it in the same terms as I'm asking.

I'm surprised because when checking the conditional is_page() in a function executed through my functions.php file, it returns false when evaluated in the page for posts page.

I was so surprised, that I have checked twice in the DB if WordPress has changed the post_type for this page (lol), but obviously, it is still a page, so... why the conditional is_page() is returning false if it is indeed a page?
