Again, a doubling of human knowledge should result in different outcomes in areas where that knowledge is applied. A lot of money is spent in improving our knowledge of certain cancers. If we double our knowledge, treatment of cancer should have a beneficial effect--improved survival rates being one effect we can measure.
A Google news search on cancer survival rates shows evidence of this. From Canada, the National Post reports that "the death rate for breast cancer for Canadian women has fallen 25% since 1986, when organized breast screening programs began being rolled out across the country." Apparently, this reduction is down to human knowledge from the early 1980's (beneficial effects of mammography) being dispersed through the wider population. Again, to me this counts. This is good news, great news. But again, if we keep a 5-year clock ticking, this news will disappoint, as it shows nothing remotely indicating a doubling of human knowledge within that timeframe.
Similarly, MedicineNet says, "Statistics (released in 1997) show that cancer patients are living longer and even "beating" the disease. Information released at an AMA sponsored conference for science writers, showed that the death rate from the dreaded disease has decreased by 3 percent in the last few years. In the 1940's only one patient in four survived on the average. By the 1960's, that figure was up to one in three, and now has reached 50% survival." So we see a doubling of the beneficial effect, but over 60 years, not five.
More encouragingly, St. Jude's Research Hospital shows 5-year survival rates for some cancers since 1962, and some of them might just qualify as 10-year doubling (pause to experiment on how to present this information... Okay, got it--click on the image to enlarge to readable size).
Again, a miracle, but it doesn't fit a 5-year window--it's 10 years for the best performing cancers.
