"Scientifically Proven"

Some phrases annoy me greatly. Particularly irritating is "Scientifically Proven".

It appears in a television advertisement for something or other - I've never paid it enough attention to find out what is being advertised.

Scientific research does not prove things true; it tests hypotheses, and at best provides grounds for accepting them as a basis for further investigations.

I also  note the use of 'proven' instead of 'proved', hinting at the solemnity of legal proceedings.

I must find out what commodity is being advertised, so I can make a point of not buying it.
