Hide all featured images on blog page

I know this is probably a simple fix, but can you tell me how to hide all featured images on a blog page? I still want the images to show up elsewhere on the site; I just want to hide them on the blog page. Most often the featured image is simply a headshot of the speaker/author, and the full-width format of the featured images on the blog page means we’re left with a bunch of absurd close-ups.
