Dr Smith has set out her credentials as lead researcher and writer for the Canadian Thyroid Patients Campaign. For those interested :
I serve as an associate professor of communication at the University of Calgary. I research thyroid mainly as a patient-advocate and secondarily as a scholar of rhetoric who analyzes the argumentation (logic, reasoning) and the ethics of thyroid science and policy (thyroid therapy guidelines). I am not a biological scientist or health professional. My research in thyroid is as an avid reader of thyroid scientific literature published in journals and medical textbooks.
She certainly shows logic and reasoning to the best extent.
