Stefan is conducting research on gene therapy. His primary source of information was the government website for the Human Genome Project, which was a thirteen-year project conducted by the US Department of Energy and the National Institutes of Health. Scientists from several different countries participated in the project.

The information gathered is

unreliable because it came from a website.
reliable because the website has an official name.
reliable because it came from a government website.
unreliable because the website includes the work from a different country.

When looking for the information online there is a need to perform a background check of the object offering the information. For the scientific information, the information given on the websites of known sources like government institutions, scientific institutes, and research facilities, which offer complete understanding into their methodology, data, and sources is the one, which should be trusted. In the given case, Stefan is getting the information from a big database formed by an international team of experts in genetics, which has been rechecked and permitted by the scientific community.
