In this episode, Therese Markow and Dr. James Alcock discuss what near-death experiences are and the increase in them in recent years due to improvements in medical technology. While near-death experiences (NDEs) have been known about for a long time, we, as a scientific community, are starting to understand more about what they mean for neurological processes. However, despite knowing the science of what is happening, NDEs and how they are experienced are subject to one’s own beliefs, context, and even religious framework. Dr. Alcock and Therese also discuss the relationship between...

When we hear the term tumor or cancer, the image that often comes to mind is a bunch of bad cells next to normal ones, and growing. Like many things, it's just not that simple. How do the normal cells turn bad? Can our immune systems detect the cancer cell and kill it? Why does some initially successful chemotherapy stop working? Why does cancer spread? These are all great questions, since cancers of one kind or another will affect so many of us either as patients, friends, or loved ones. Well, basic science is providing some critical answers. In today’s episode, Therese Markow and Dr. Ajit...

In this episode, Therese Markow and Dr. Brandon Sparks discuss the phenomenon of involuntary celibacy (incels). Dr. Sparks, an applied forensic psychologist, explains that incels are men experiencing long-term involuntary celibacy, often due to social exclusion and bullying during adolescence. Incels, primarily aged 18-30, are less likely to be in education or employment. The term "incel" originated from a woman's project at Carleton University. Incels often self-identify online, where they discuss the "Black Pill" philosophy, a nihilistic view of society. Dr. Sparks highlights the need for...
info_outlineWe all believe in something, from Santa Claus, to the global shape of the earth, to babies needing to be taken care of for survival. While some of our beliefs are intuitive or have evidence, many are not. Sometimes the evidence that we believe to be true is faulty. In this episode, Therese Markow and Dr. James Alcock discuss how these beliefs are built, how we interpret situations to create beliefs, and why we, as a society, have so many common beliefs. As humans, we like to believe we are rational beings, but so many of our beliefs are happening automatically, without our conscious thought or from common teachings that we are all exposed to from those in authority. Therese and Dr. Alcock also discuss further complications regarding belief, such as conspiracy mentalities, imagination inflation, and memory contamination and the role that these elements of complication can play in trying to suss out what to believe in this world full of many shades of gray.
Key Takeaways:
-
We cannot learn everything in one lifetime so, as a society, we come to rely on authorities and shared, inherited beliefs.
-
There is no evidence that people can bury trauma. The problem with trauma is people can’t forget.
-
Due to mental desire to belief and idiosyncratic movements, humans often see things that are “magic” or “unexplainable” due to our own actions.
"The problem is, if we don’t have the capacity and we don’t have the motivation to critically examine the evidence, then we won’t distinguish between evidence that really is factual and evidence which is wrong." — Dr. James Alcock
