Finger length and penis size

My sister told me this morning that men with longer fingers have bigger penises. I didn't believe her so I looked it up. I read multiple articles about the subject. It's actually the difference in ring finger and index finger length. Like, if they are closer to the same length, the man supposedly has a longer penis. Do you think this is true? I'll post the article.
