Like others have said, wikipedia can be used as a starting point, but only to find actual references. For most academic topics wikipedia will cite pivotal papers which should be looked at. From those you can draw your own conclusions and gain a greater understanding.
Another thing to be wary of is in certain areas, some individuals may wish to push their work more than others, leading to a bias in the wiki article. Find a range and variety of papers to reference to ensure you have a full understanding of what you're researching.
