Michio Kaku ()
I have only been listening to the show for six months or so, and have been thoroughly enjoying it. Thank you for making it so great. However, this week's interview with Michio Kaku was very disappointing. I have a decent understanding of several of the topics he was talking about by virtue of being in a neuroscience lab, and he was so far off in characterizing our understanding of the brain. Kaku conflated DBS treatment of Alzheimer's Disease with the Ramirez optogenetics experiment, which are completely different efforts with different goals. Relating to implanting a memory, we are so far off from reaching that point in humans it is ridiculous. The simplest level of this would be activating an existing engram created by the individual, and I don't think we'll even reach that point in humans within my lifetime (for context, I am 23). Kaku goes on to explain bottom-up learning, but I don't think he understands for how long we have been implementing machine learning[1]. He also seems to think that we will 'understand' the brain once we have mapped all the connections, which would fly in the face of long-term potentiation (LTP) or our understanding of Working Memory. His grandiose ideas for using of imaging for understanding psychological diseases are nice, but ignore the sensitivities of such diseases and all that imaging cannot show us. There's more inadequacies, and I am sure as I learn more about the brain, I will be able to identify more. It really seems as though Kaku is far more interested in the science fiction implications of neuroscience than anything else. And that's great — we need to discuss those implications for the future, but we need to do so competently and acknowledging what can or cannot be done. And don't get me wrong, there's fantastic and amazing things happening in neuroscience every day, things like this[1]. But as skeptics, I think we should move one step at a time and constantly challenge and evaluate the evidence brought forward by people like Kaku. Again, I love the show and thank you for everything, Omri
Dealing with Negativity ()
How do you honestly cope with the Intelligent Design frustration? I ask this because I saw a YouTube video where a simple audience question was asked — what scientific test is used to validate Intelligent Design This was…a VERY straightforward question. Rather than answering it, the person went on to discuss the meaning of 'test' and the validity of science using as much convoluted logic as he could possibly muster. It went on for about 10 minutes and the question was never answered (and yes I know they have no idea how to answer it since there IS no test for ID). I honestly wanted to shout out and say 'answer the FUCKING question please.' I can't see how you guys can take this because there are times where I am mystified Seriously, how can you take it sometimes? Dave Fernandes Rolla MO Dear Steven, Bob, Rebecca, Jay, and Evan, First off I wanted to thank you for all being a sound, reasonable voice in what feels like a largely unreasonable society. My question for you comes from a feeling I got while listening to your recent episode in which you discuss 'The food babe'. I found myself uncomfortable with anger. Almost to the point where I had to take a walk around the building to work off some frustration. I feel like the voices of people like Vani drown out the voices of those people should be listening to. I see people on her blog and youtube praising her for her 'Research,' and citing shallow reasons she makes good arguments (one of which literally being because she's attractive) I can't help but see this and feel overwhelmed. It almost feels pointless to try to work against these people. My question is do you also feel this way from time to time, and how do you deal with it? Thank you for all your hard work -Brian Anderegg United States
Name that Logical Fallacy ()
As a vegan skeptic, I often find myself in arguments with omnivores who seem to rely almost exclusively on logical fallacies to justify their diets. Examples include: - 'Humans have been eating meat for tens of thousands of years…' (Argument from antiquity) - 'Lions hunt and kill animals. Humans are no different It's natural to eat meat.' (Naturalistic fallacy) One I hear a lot though, is the question of 'Well what would we do with all the animals that already exist? Should we just kill them? Stop them from reproducing?' Of course, this has nothing to do with the question of whether it's ethically acceptable to raise and kill animals for food. It may be an unsolved problem, but it doesn't justify a continuation of that policy. So is this just a red herring? Non-sequitur? The latter also appears a lot, as in 'Harvesting vegetables kills insects!' and 'Vegetables are bad for the environment, too!' Thanks! –Steven Yenzer United States
