Credits and Caveats
This form and query are based on 2003 Book "Google Hacks by Tara Calishain and Rael Dornfest. The underlying concept of using Controversy to probe into the Analytic Web was explored in the 2004 experimental study "Do Search Engines Suppress Controversy?" article in "First Monday". The form was created by Susan L. Gerhart in 2005.
Here are a few caveats:
- The Controversy Discovery Engine is meant to help you start exploring a topic for controversies, opinions, evidence, and authorities by adding common synonym and useful extended terms. This will often drive your search into references to scholarly papers, including abstracts. As always, it's your responsibility to double check any facts or theories, especially because the expanded search terms may lead to pages with crack pot theories or diatribes.
- While this HTML form has worked for fifteen years, Google may change its search interface at any time. The search form was tested on FireFox, Brave, and Edge browsers on Windows 10in late March 2020. The form was created and tested with the free screen reader NVDA, also using VoiceOver on an iPad.
- This web page uses the simplest possible HTML, without styles, to p hermit easy modification. Try your own synonyms or terminology.
