I assume that the question here refers to the process of evolution. The "helpful variations" are small mutations that allow the organism to have a small advantage over other - and this organism can then pass this variation to its children better than other organisms, meaning that with time, more organisms will have it. This will accumulate over time and the percentage of organisms with this mutation will increase.
The RR technique or the Randomized Response can be used to help ensure that individuals answer sensitive or self-incriminating questions honestly. It is developed by Warner (1965), which aims to eliminate or at least minimize non-response and dishonest answering by survey respondents. This is accomplished by separating the response from the respondent by introducing a controlled measure of chance or uncertainty, which amounts to randomization of the answering process. This protects the identity of the respondents, at the cost of introducing a degree of uncertainty into the responses.
