Also, causal principles help decide if it will work in a certain setting and if it will cause the result that someone was wanting. “Causal principles fix what causes what.” They believe that the effects of causes are produced in some systematic way. They argue that a policy will not work if there is no causal principle connecting the two. An example they use is “Getting lung cancer is correlated with owning ashtrays. But buying ashtrays will not bring on cancer.”
Another thing they argued were examples of where doing “here”, didn’t end up working there. Examples of this are the failures of the Intensive Nutrition Program in Bangladesh and the smaller class sizes in California. Both were based on the success of another program before them. The reason they failed is because of the failure to see success beyond that it had worked somewhere else. In Tennessee small classes led to better reading levels, but not the same effect happened in California. The California example shows that someone should think more about support factors. When you have a smaller number of students in each class, you will have more
