Is it Usual to Get a Second PhD in a Different Field?
The pursuit of a second PhD in a completely different field is indeed very unusual. While it's not impossible, most individuals find it difficult to justify the time, financial investment, and the societal perception of such a move. In Europe or Australia, for example, even doing a second PhD in the same field can be quite challenging due to institutional and funding constraints.
Unusual but Not Unheard Of
Despite the rarity, I personally know a few individuals who have successfully completed second PhDs in different fields. For these individuals, the decision was driven by genuine personal or professional motivations, though financing was not a primary concern. Paying for a second PhD is strongly discouraged. Instead, pairing up with a mentor or collaborator in the new field can provide a viable pathway to further research without the need for a second degree.
The rationale for a second PhD in a different field typically must be compelling. Most professional or academic advisors would advise against it unless there is a valid reason. The financial burden of student loans can be immense, making such a pursuit even more daunting.
Exceptional Cases
There are a few exceptional cases where a second PhD in a different field makes sense. For instance, medical students or professionals in training might opt for concurrent MD (Doctor of Medicine) and PhD in fields like biochemistry. This dual degree structure can provide a unique advantage and personalize the educational experience.
Historically, there have been notable examples of individuals pursuing second PhDs in different fields for career shifts or professional licensure. For example, Fr. Georges Lema?tre, who initially pursued a PhD in theology, later completed a PhD in physics at MIT. In another notable case, my friend Lucinda studied research psychology and later returned to complete a PhD in clinical psychology, several years later, which was specifically required for her career progression.
Conclusion
While a second PhD in a different field is unusual, it is not entirely unheard of. The decision to pursue such a path must weigh the reasons for doing so, the financial implications, and the potential professional benefits. For most individuals, the time and resources required for a second degree might be better allocated to other career or educational pursuits.
