Even doctors are not reading or understanding tests results right in many cases. Sometimes they blame on technology - like X
, CT Scan, and so on, you know. My point is then what doctors are actually doctoring? A person with good common sense can tell you if technology is better, for instance, CT Scan is better than X-Ray. Like when ask, could you tell me whether Monalisa (picture of Leonardo) is smilling or crying? Then it is up to the observer to find out by looking at the picture.
