Does same content affects ranking

I connects discourse community with my wordpress, that’s why every content posted on wordpress, automatically posted on the discourse community and that’s a great thing.

But, I simply want to know, when both pages have same content, does it affects google ranking.

Every single help really appreciated.
Thanks

Thanks @mpalmer, It doesn’t affects my ranking.

One more question, Is there a way in wordpress plugin so that the line “Originally Article is written at” published in the end of the article instead of in the starting of the article.

Yes, you’ll need to do a little custom coding, but you can use WordPress hooks to change the templates:
