Many research projects are never formally published because they lack mass appeal, fail to show significant results, or are not held to the same rigorous standards that these journals require.

ACTUALLY a Significant Number of Studies are Never

published, because the author couldn't afford entry fees to the "Publishing Machine" which rules the science world. There are a significant number of studies which are excellent, which were done by financially poor scientists.

Fortunately, there are systems being created now which allow scientists to publish their works without having to pay substantial fees. :)
