The Existence of planetary effects, however, exemplified by MARS and sports champions, is denied by skeptic circles. The grounds for this point of view are traced to biased investigations: The skeprics tend to work out insufficient designs, to collect unfavourable dara, to prevent planetary effects from emerging, to ignore positive results if they show up, or to obliterate them by reinterpretation and to defame authors whose results confirm planetary effects while providing evidence for the skeptics' unfairness. The conclusion is that an increasing number of unprejudiced scientists is required who are ready to acknowledge the existing positive evidence while augmenting it by replications.
