<p>Does stanford not want supplement materials, like a research design, because there does not seem to be a place for one?</p>
<p>They don't accept any extra materials, and they are very strict about it.</p>
<p>They will take another recommendation though (which I used).</p>
<p>And nothing prevents from you from just sending in the materials if they're EXTREMELY OUTSTANDING. But make sure to include a very professional cover letter that explains everything and makes you look good!</p>
<p>On the website they cleary state no extra info would be accepted</p>
<p>But if you really think your stuff is good and want to take a risk, go ahead. Make sure its really good though</p>
