Very often. Scientists make a lot of mistakes. Cause they don't do some of their experiments with love.
Scientists do that because they are skeptical about other scientists' work. They do not usually believe what other scientists have concluded, so other scientists come up with a hypothesis (or simply state a question) as to contradict, or theorize why another scientists' work and conclusions are wrong. In short: Scientists are skeptical and do not believe what another scientist has come up with as a conclusion.
based on observation of what is wrong with the work of other scientists
The scientists often revise the hypothesis.
Good science is reproducible, meaning that other scientists should be able to conduct the same analysis and get similar results. If scientists try the experiments and get different results, then it often means that the original publishers did something wrong.
Scientists are often trying to find out whether certain factors changed or remained the same.
