Analysis of prostate cancer test results is carried out with prostate-specific antigen (PSA) tests. The psychologists conducted public awareness interviews in different country level on benefits of PSA tests. Russian Men came out highest on the lower level of misinformation at 23 %.
The psychologists tested the physicians on their understanding of benefits and chance of occurrence of a disease given a positive test (positive predictive value). The test was about interpreting breast cancer results. The physician gave varied (wrong) statistical percentages on prevalence, sensitivity and false-positive rate. The psychologists viewed this as a problem of statistical interpretation skills (such as conditional probabilities).
Risk estimation information becomes a major problem. For example in the prostate cancer screening, where ten percent of the women have cancer, a European press presented the data as a twenty percent 20% relative risk reduction. They did not state the fact that this was equal to absolute risk reduction from 3.7 to 3.0 in 1,000 which translated to non transparent risk communication.

The psychologists concluded that medical schools should clearly teach statistical thinking rather than statistical rituals. Children should be introduced to probability and statistical literacy early enough in their life. The society should advocate for transparent risk communication. The psychologists further recommended replacing single-event probabilities with frequency statements, relative risks with absolute risks, survival rates with mortality rates, and conditional probabilities with natural frequencies. These measures will help shape the attitude and effectiveness of the medical world.
