Cognitive Science of Social Media, Technology, & Meaning | Mark Miller & Ben White (EP 38)
[Re-uploaded podcast with audio at the start fixed]
Mark Miller is a cognitive scientist, and Ben White is currently
completing a PhD in the philosophy of cognitive science.
From social media to AI to smart environments, technologies are
transforming our lives. How can we understand the profound positive and
negative effects they have? Cognitive science provides a framework to
understand how these technologies influence our minds.
In this podcast, expect to learn about the benefits and harms of social
media, how social media subverts our natural drives, beliefs, and
expectations that typically guide us through the world, how we are
natural-born cyborgs that instinctively embrace technologies, and how we
should think about ourselves and our relationship with technologies in
this context.

a cognitive science and psychological framework, why the placebo effect
might never be separated from so-called "real" or "biological" effects,
how placebos may have helped ancient cultures with their medicine, and

How Understanding The True History of Capitalism Helps Fix It - Erica Schoenberger (EP 39)
Erica Schoenberger is an economic geographer and environmental
historian.

through wars and the projects of the rich, disrupting the lives of many.
How can we come to understand the true history of capitalism?
Expect to learn about how markets were created by states to help fund
wars, how markets and states are intertwined and rely on each other, how
capitalism and money have evolved over time, modern economic systems
and unnecessary work, the economy's need for perpetual growth, how to
keep the good parts of capitalism without the bad, and more...

Reality, Illusion, Skepticism, Love & Beauty - D.C Shindler (EP 36)
David C. Shindler is a Professor of Metaphysics and Anthropology at the
John Paul II Institute, Washington, DC.
If modern physics tells us that time and reality are not as they appear
to us, what is real? Can we ever know and touch reality? Relatedly, does
objective truth exist (or is it just in our minds)? This podcast
explores these questions through philosophy.
In this podcast, we consider the nature of truth, whether reality could
be an illusion, how to deal with skeptical over the realness of truth,
as well as how love, beauty, and goodness, relate to these questions.

Meditation And Pure Consciousness Experiences - Toby Woods | EP 23
Toby Woods is a scientist at the Monash Centre for Consciousness and
Contemplative Studies.
Subjective experience is notoriously difficult to study scientifically.
This is even more the case for subjective experience in meditation and
for this reason it has not been widely examined. In this podcast I am
joined by Toby Woods, who is part of a growing movement to examine
meditation experiences in a systematic and fine-grained manner using
scientific methods.
In the podcast we discuss the experience of "stillness" or "pure
consciousness" in meditation, including the content that is present and
absent, and we compare the experiences attained in different types of
practices. We also look at the benefits of accessing the stillness and
the risks and benefits of practising meditation more generally.
