 Regarding the changes to the entry on differential diagnosis - which I did write, 
 I consider them to be useful changes - NOT spam.   

 Naturally, if you disagree with the additions to the Differential Diagnosis 
 page, then - since it is your page - you should feel free to change or delete them.   
 Alternatively, if you have different views on some aspect of the topic, 
 but still are willing to acknowledge the potential relevance of some of the 
 information that I've added, perhaps you wish to moved my additions to some 
 other section of your page, or supplement it with additional information of your own, 
 or indicate that there is disagreement on some aspect of it. 

 I acknowledge that many of the points that I brought up on the topic of differential diagnosis are quite straightforward, but I think that they are still relevant and 
 useful. 

 Some of the other points - regarding the use of Bayes rule to rigorously use 
 conditioning information (such as risk factors) to evaluate the likelihood 
 of various diagnoses - is unfortunately not known by many practioners -  
 although it is actually the theoretically most correct way of evaluating 
 and using such risk data. 

 The other point regarding cognitive biases in medical decision making 
 is a very important one, and has been the subject of over 25 years of 
 research at many top Universities (like Stanford and U.C. Berkeley). 
 I urge you to take a look at some of the biases on the list of cognitive biases, 
 particularly availability bias, representativeness bias, ignoring bases rates, optimistic overconfidence bias, and a whole host of other very well researched biases that have 
 a ongoing profound impact on clinical decision making. 

 Perhaps it would be best if these would be moved to a different subsection  
 of the page, and you should certainly feel free to do so, or if you 
 give me permission, I would be happy to do so. 

 Thanks.
