The beautiful thing about the blog-world is that anyone can now witness what has been happening at lunch tables all across American institutions of higher education for decades. No need to get a PhD, or to by a soggy tuna salad sandwich to partake.
I highly recommend this series of exchanges (follow the links) between Tyler Cowen and Alex Tabarrok. No mind whether you understand a word of what they are saying, pay attention to:
- The questions they are asking
- The scientific nature of their claims and evidence
- Positing of alternative (and largely testable) theories, rather than calling each other names
- The healthy dose of respect each has for the complexity of this issue
