One last note. In North America, at least, there is a widespread use of using a singular form like "there is" and "there was", without regard for the subject item or items, and this "there is" is often shortened to "there's": There's three apples on the table! Could you please clarify this mess?

I had written a paper with the sentence "There is also social proof in how the man with the pizza ends up with an attractive women". I had lost marks due to the fact it is poor English to start sentences with "There is" or "There are". I want to double check this is true because the prof actually is not fluent in English herself.
To be fair to the O.P., an Ngram shows "there isn't" seems to be preferred over "there's not," so there might be some merit to the assertion that one seems more awkward than the other in certain situations. But I stand by my answer: there are times when either would beg for improvement, and other situations where either works just fine.
