Who cares if I can run a formula&#x2F;program that tells me Y from X if I can&#x27;t understand&#x2F;trust the program&#x2F;formula ?<p>If you think that stuff like economics&#x2F;climatology&#x2F;etc. has the same level of rigor and validation applied to it as established and verified theories from hard science then boy do I have some bad news for you (struggling for SD 2 as ideal vs SD 5 for eg.).
