The Reality Check Episode 56

Umami/MSG + Ray Hyman Interview + Baldness Myth

UMAMI

Part 1: 

Umami, also referred to as savoriness, is one of the basic tastes sensed by specialized receptor cells present on the human and animal tongue. Umami is a load-word from Japanese meaning "good flavor" or "good taste". In as much as it describes the flavor common to savory products such as meat, cheese, and mushrooms, Umami is similar to Brillat-Savarin's concept of osmazome, and early Western attempt to describe the main flavoring component of meat as extracted in the process of making stock.

The Umami taste is due to the detection of the carboxylate anion of glutamic acid, a naturally occurring amino acid common in meat, cheese, broth, stock, and other protein-heavy foods. Salts of glutamic acid, known as glutamates, easily ionize to give the same carboxylate form and therefore the same taste. For this reason, they are used as flavor enhancers. The most commonly used of these is monosodium glutamate (MSG). While the Umami taste is due to glutamates, 5'-Ribonucleotides such as guanosine monophosphate (GMP) and inosine monophosphate (IMP) greatly enhance its perceived intensity. Since these ribonucleotides are also acids, their salts are sometimes added together with glutamates to obtain a synergistic flavor enhancement effect. 

Ray Hyman

Part 2:

Ray Hyman is Professor Emeritus of Psychology at the University of Oregon and one of the leading figures of modern skepticism. He was a founding member of the Committee for Skeptical Inquiry (formerly CSICOP). He has been a consultant with the U.S. Department of Defense, helping investigate parapsychology for the government and is the author of many books, such as The Elusive Quarry, and many articles in the scholarly literature, such as his popular manuscript that teaches people how to appear to have psychic powers by using "cold reading." A former magician and mentalist, he has been featured on the cover of The Linking Ring, the magazine of the International Brotherhood of Magicians. Hyman was a co-recipient of the 2005 Robert P. Balles Prize in Critical Thinking, and also CSI's In Praise of Reason Award. For almost 20 years, he has run the popular Skeptics Toolbox, which trains rationalists in the best methods of advancing skepticism in our society.

In this conversation with D.J. Grothe, Ray Hyman recounts the history of his many critiques of the various Ganzfeld Experiments, which are scientific tests of psychic ability. He details his assessments of the later "Auto Ganzfeld experiments." He shares his evaluations of other various research projects in parapsychology, and levels criticism against some skeptics who have too hastily dismissed parapsychology's findings. He talks about his beginnings as a magician-debunker, and as a mentalist, and how he got involved in applying magic to his skeptical investigation of parapsychological claims. He explores whether or not the government should make fortune-telling illegal. He explains how leading scientists can believe in the claims of parapsychology, even without sufficient evidence. He describes some of his experiences with Uri Geller. He talks about the ethical implications of teaching non-magicians the art of cold-reading. He reveals ethical problems he has had with the Psychic Entertainers Association, and how giving psychic readings may cause real harm to clients. And he talks about how he may disagree with James Randi as regards the usefulness of magicians in conducting psychic research. - From Point of Inquiry 

Science Myth of the Week:

Sadly, it's much easier for men to get blad than women, it's because they have two Xs, and we have one X and one Y, so it's easier.
