How to Use the Feynman Technique to Identify Pseudoscience

Last week a new study made headlines worldwide by bluntly demonstrating the human capacity to be misled by “pseudo-profound bullshit” from the likes of Deepak Chopra, infamous for making profound sounding yet entirely meaningless statements by abusing scientific language.

The researchers correlate believing pseudo-profundities will all kinds of things Clever People Aren’t Supposed to Like, and one suspects the paper wouldn’t survive replication. So why is this a job for Feynman?

Richard Feynman (1918-1988)

This is all well and good, but how are we supposed to know that we are being misled when we read a quote about quantum theory from someone like Chopra, if we don’t know the first thing about quantum mechanics?

Actually, one can often detect BS without knowing much about the topic at hand, because it often sounds deep but doesn’t reflect common sense. Anyway, from Feynman,

I finally figured out a way to test whether you have taught an idea or you have only taught a definition. Test it this way: You say, ‘Without using the new word which you have just learned, try to rephrase what you have just learned in your own language. Without using the word “energy,” tell me what you know now about the dog’s motion.’ You cannot. So you learned nothing about science. That may be all right. You may not want to learn something about science right away. You have to learn definitions. But for the very first lesson, is that not possibly destructive? More.

It won’t work because many people who read pop science literature do so for the same reason others listen to Deepak Chopra: They want to be reassured against their better judgement or the evidence.  Whether it’s that there are billions of habitable planets out there or that chimpanzees are entering the Stone Age, or that everything is a cosmic accident, or whatever the current schtick is.

And Feynman won’t help them, nor will a bucket of ice water. And it’s not fair to drag ol’ Feynman into it just because he said some true things like,

The first principle is that you must not fool yourself and you are the easiest person to fool.

Give the guy a break.

That said, Feynman (1918–1988) may have, through no fault of his (long-deceased) own, played a role in getting a science journalist dumped recently on suspicious grounds. See “Scientific American may be owned by Nature, but it is run by Twitter

Z, In one word: nonsense. You refuse to examine the critical point -- OOL, and the implications of the challenge to build FSCO/I with blind chance and mechanical necessity. That is, you keep on ignoring the point that there is a threshold that is readily shown, once we have 500 - 1,000 bits of FSCO/I we are at a point where the atomic and temporal resources of the sol system then the observed cosmos will be utterly incapable of finding isolated islands of function. Where requisites of specific function in a highly contingent context will confine us to clusters of working configs in the space of possibilities. In short, evolutionary materialist scientism is unable to get us from a Darwin pond etc to viable FSCO/I rich cell based life. But, the FSCO/I is an empirically confirmed, needle in haystack plausible, reliable signature of design. This needle in haystack problem compounds for origin of body plans and similarly complex entities. Where, the stat thermo-d speaks straight to config and phase spaces of v large size and highlights why spontaneous equilibrium comes about because of overwhelming relative statistical weight of clusters of microstates. So, we have a pretty good reason to see why systems, isolated, closed or open tend to move to such clusters unless otherwise constrained. But, commonly we see wiring diagram based assembly of such FSCO/I rich configs. By intelligence acting through design. This, you patently refuse to face: there is good reason to hold FSCO/I (that is a descriptive abbreviation . . . ) a signature of design. Above you had to admit that you cannot get to FSCO/I by blind chance and mechanical necessity in a Darwin pond etc. Again, the only empirically confirmed solution on how to get to FSCO/I is design. But no, you want to dismiss so you go off after a tangent that conflates a crystal with organised, functionally specific complexity. All in the obvious context, conclusion to reject design in hand, let's just find a rhetorically convenient excuse to make a dismissive talking point. Pop goes the weasel, you just did that. Here is what the rhetorical stunt you just pulled looks like: >>Oh, you cannot give an exact number on an irrelevancy -- though it is patent that the FSCO/I threshold has been vastly surpassed over and over again to get to the point of a functional brain, so let's ignore the substantial point and pretend all is well with the evo mat mythology.>> But, all you have really shown is that you are locked into a failed paradigm in the teeth of an adequate response on the substantial point.

Z, still side tracking I see. There is no need to try to estimate values for diamond crystal vs brain tissue, when we already know that the FSCO/I in the cells of the brain is already well beyond a relevant threshold. And, the statistical thermodynamics considerations on config spaces and islands of function are already more than adequate, once we recognise that a diamond crystal structure is mechanical necessity leading to a metastable structure which contrasts with the non periodic, wiring diagram based highly informational assembly involved in molecules, cells, tissues and neural networks. We cannot quantify the whole [an overwhelmingly complex calc] but there is far more than enough in hand to see that we are far, far, far beyond the 500 - 1,000 bits of functionally specific complex organisation and associated information where blind chance and mechanical necessity are hopelessly implausible and the only observationally warranted explanation is design. Remember, cellular functionality is a config constraining macro observable, locking us to islands of function in config spaces that go far beyond astronomical blind needle in haystack search challenge. The threshold calc is good enough for reasonable purposes, to strain at a gnat while swallowing a camel is pointless -- apart from playing at the useless rhetoric of selective hyperskepticism -- once such is in hand. Finally, the proper place to begin is the root of the tree of life, OOL, which is decisive, it puts design at the table as of right as best empirically warranted explanation from the outset. That is what is being studiously ducked, and it is telling. KFkairosfocus

Mung, Happy new year to you and all others here at UD. I suggest the best answer is in Orgel and Wicken. Brains are organised in a clearly goal and function oriented pattern in accord with implied wiring diagrams and associated information. The significance of which becomes evident from the sinister sniper's practice of the head-shot. The diamond or graphite crystal is ordered per the mechanical necessity of crystals and relevant PVT etc circumstances. Those worthies also contrast randomness as with tars and masses of small crystals in certain rocks. They warn that conflation of the first two -- an obvious agenda of Z -- has no credible future. And, given the state-based rather than path based functional nature of entropy, it makes sense to partition its components, indeed in classical thermodynamics, measurements are relative to changes from reference states. Thus, a conceptually oriented analysis that unifies information and organisation on the one hand with entropy, order and the second law on the other is an eminently reasonable scientific exercise. So, it is unreasonable to try to insist on conflating that which is observationally and conceptually distinguishable within the ambit of a unifying analysis. Remember, Shannon's analysis unexpectedly pointed to a strong parallel c 1948. By 1957 on, Jaynes had hit on an analysis that was going to be very fruitful, moreso than simple negentropy . . . though this last is not exactly without merits. Z's ideological lockout tactic is 40 - 50 years behind times, once Jaynes weighed in with the information bridge and once we got to the Orgel-Wicken distinction. Actually, Lewis from 80 or so years ago had powerful points, as Wiki has been forced to concede. KFkairosfocus

Z, more and more misdirections. Start with ATP synthase, which is pivotal to life as ever so much of life chemistry is endothermic. Address the FSCO/I-rich units in metabolism, and the FSCO/I in the process-flow network itself. Do not overlook coded information and how it works in the protein assembling ribosome. Start with the darwin pond or the like. Where is that FSCO/I coming from before there is a self-replicating, von Neumann kinematic self replicating cell. Indeed, that too is to be explained. On what actual empirical observation does it become plausible to infer or hold that this FSCO/I comes about by blind chance and mechanical necessity without any intelligent configuration? KF PS: You are also trying to tag to me a statement that comes from Wikipedia speaking against general interest. Besides it is correct, adding heat to a system increases the number of ways mass and energy may be arranged at microscopic level. In a simple but classic case, this is the Boltzmann expression that is on his gravestone: s = k log W. If you object to it, kindly explain how Boltzmann and Gibbs et al went wrong in founding statistical thermodynamics.kairosfocus

kairosfocus: a word game Not at all. You brought up heat engines, which don't require design, but do require a source of energy. kairosfocus: the issue is to account for the FSCO/I rich heat engines and/or energy conversion devices that carry out key metabolic processes in the cell. From the viewpoint of thermodynamics, energy is required. And complex structures are often less thermodynamically ordered than natural structures, such as crystals. Other than that, thermodynamics doesn't have much to say.Zachriel

Z, did you see where I both pointed to tropical cyclones as convective-coriolis systems and in what you clipped, spoke of how "heat engines commonly are carefully organised and FSCO/I rich"? (As in, as opposed to universally?) Your objection is misdirected, but of course it could lead an inattentive reader to think I did not make a careful distinction. But, I did. And that highlights the real -- and unanswered -- issue: there are a LOT of heat engines and energy conversion devices that are FSCO/I rich, ranging from steam engines and auto engines to the molecular nanotech of the cell. That requires serious explanation, and the pattern remains that once we directly know causal origin, FSCO/I is a reliable sign of intelligence, backed up by the needle in haystack challenge. For that, so far it is crickets chirping. KF PS: Much the same problem arises with the diversion from the issue of origin of the cell including its self replicating facility. Obviously, cells replicate in a chain and per conventional timeline have for 3.5 bn y. But that says zip about the origin of those FSCO/I based facilities in Darwin's pond or the like. With, the needle haystack challenge looking right at you. Which is what was on the table and it is what you again sought to divert attention from. Such tactics speak volumes. PPS: Especially coming hard on the heels of having to admit no account for origin of the relevant FSCO/I, as Mung reminds.kairosfocus

Mung (Attn AC et al): Before we get to a self replicating life form, we have to go through the chemistry and physics of a Darwin pond or the like prebiotic environment. And, the origin of the molecular nanotech of life and associated information has to be cogently explained. With thermodynamics issues including statistical and information ones, up front centre. If you do not get from chem to bio chem, the game is over at the beginning, and thermodynamics is central. Thing is, this will give some key lessons in the difficulty of finding deeply isolated islands of functional organisation in beyond astronomical config spaces, by way of blind chance and necessity needle in haystack searches where for just 1,000 bits worth, the search capability of the observed cosmos of 10^80 or so atoms, for 10^17 s at 10^12 - 14 tried per second each as observers, will be as one straw to a haystack that dwarfs the observed cosmos, as we here deal with 1.07*10^301 possibilities. That is what is being ducked. Then, when we get to the origin of body plans, thus integrated networks of organs, tissues, cell types and requisite proteins and D/RNA, we are looking at the same challenge to be solved in a sol system of some 10^57 atoms. Where 1,000 bits is about as complex as a typical protein. Where also, protein fold domains are going to be deeply isolated in AA sequence space. I am not even going to bother to discuss how we get to codes and to embryologically and ecologically viable body plans. Thermodynamics and energy flows obviously apply and there is a tendency to glibly suggest that open systems with energy flows remove that as an obstacle. Not so fast. First, consider Clausius' isolated system with two subsystems . . . I here clip App ! my always linked:
a] Clausius is the founder of the 2nd law, and the first standard example of an isolated system -- one that allows neither energy nor matter to flow in or out -- is instructive, given the "closed" subsystems [i.e. allowing energy to pass in or out] in it. Pardon the substitute for a real diagram, for now: Isol System: | | (A, at Thot) --> d'Q, heat --> (B, at T cold) | | b] Now, we introduce entropy change dS >/= d'Q/T . . . "Eqn" A.1 c] So, dSa >/= -d'Q/Th, and dSb >/= +d'Q/Tc, where Th > Tc d] That is, for system, dStot >/= dSa + dSb >/= 0, as Th > Tc . . . "Eqn" A.2 e] But, observe: the subsystems A and B are open to energy inflows and outflows, and the entropy of B RISES DUE TO THE IMPORTATION OF RAW ENERGY. f] The key point is that when raw energy enters a body, it tends to make its entropy rise. This can be envisioned on a simple model of a gas-filled box with piston-ends at the left and the right: ================================= ||::::::::::::::::::::::::::::::::::::::::::|| ||::::::::::::::::::::::::::::::::::::::::::||=== ||::::::::::::::::::::::::::::::::::::::::::|| ================================= 1: Consider a box as above, filled with tiny perfectly hard marbles [so collisions will be elastic], scattered similar to a raisin-filled Christmas pudding (pardon how the textual elements give the impression of a regular grid, think of them as scattered more or less hap-hazardly as would happen in a cake). 2: Now, let the marbles all be at rest to begin with. 3: Then, imagine that a layer of them up against the leftmost wall were given a sudden, quite, quite hard push to the right [the left and right ends are pistons]. 4: Simply on Newtonian physics, the moving balls would begin to collide with the marbles to their right, and in this model perfectly elastically. So, as they hit, the other marbles would be set in motion in succession. A wave of motion would begin, rippling from left to right 5:As the glancing angles on collision will vary at random, the marbles hit and the original marbles would soon begin to bounce in all sorts of directions. Then, they would also deflect off the walls, bouncing back into the body of the box and other marbles, causing the motion to continue indefinitely. 6: Soon, the marbles will be continually moving in all sorts of directions, with varying speeds, forming what is called the Maxwell-Boltzmann distribution, a bell-shaped curve. 7: And, this pattern would emerge independent of the specific initial arrantgement or how we impart motion to it, i.e. this is an attractor in the phase space: once the marbles are set in motion somehow, and move around and interact, they will soon enough settle into the M-B pattern. E.g. the same would happen if a small charge of explosive were set off in the middle of the box, pushing our the balls there into the rest, and so on. And once the M-B pattern sets in, it will strongly tend to continue. (That is, the process is ergodic.) . . .
Heat engines partly get around this by being carefully organised to couple particular forms of energy to create shaft work; exhausting waste heat to a sink at lower temperature than the heat source. That way the rise compensates. But notice, heat engines commonly are carefully organised and FSCO/I rich. (We are not here looking at say a convection- coriolis entity such as a tropical cyclone.) Thus, when we look at such in the living cell, the question arises: can this be accounted for per molecular noise in Darwin's pond etc? That takes us to the statistical, needle in haystack challenge, and there is no cogent way to plausibly claim and back up with good observations, that such could reasonably spontaneously form. So, we are looking at questionable ideological imposition of a priori materialistic scientism, meant to lock out the obvious inference: FSCO/I per massive observational base, is a reliable sign of design as cause. Backed up by the needle in haystack challenge. So we see the ways in which thermodynamics principles and considerations are relevant but unwelcome. Thus the promotion of dismissive talking points about open systems. KF PS: And to get from heat engines and shaft or flow work to building FSCO/I rich entities, we are looking at wiring diagrams, assembly steps and availability of the right components in the right order, place and time. All of which is hugely information rich. It's FSCO/I all the way down.kairosfocus

Mung, you had me breaking out in laughter as I contemplated apostle Jaynes and evangelist Robertson eyeing a suspiciously large cauldron as they preach to the unwashed heathen in a Science faculty seminar room. KF PS: Even Wiki may be getting the Info view of thermo-d religion:
At an everyday practical level the links between information entropy and thermodynamic entropy are not close. Physicists and chemists are apt to be more interested in changes in entropy as a system spontaneously evolves away from its initial conditions, in accordance with the second law of thermodynamics, rather than an unchanging probability distribution. And, as the numerical smallness of Boltzmann's constant kB indicates, the changes in S / kB for even minute amounts of substances in chemical and physical processes represent amounts of entropy which are so large as to be right off the scale compared to anything seen in data compression or signal processing. But, at a multidisciplinary level, connections can be made between thermodynamic and informational entropy, although it took many years in the development of the theories of statistical mechanics and information theory to make the relationship fully apparent. In fact, in the view of Jaynes (1957), thermodynamics should be seen as an application of Shannon's information theory: the thermodynamic entropy is interpreted as being an estimate of the amount of further Shannon information needed to define the detailed microscopic state of the system, that remains uncommunicated by a description solely in terms of the macroscopic variables of classical thermodynamics. For example, adding heat to a system increases its thermodynamic entropy because it increases the number of possible microscopic states that it could be in, thus making any complete state description longer. (See article: maximum entropy thermodynamics.[Also,another article remarks: >>in the words of G. N. Lewis writing about chemical entropy in 1930, "Gain in entropy always means loss of information, and nothing more" . . . in the discrete case using base two logarithms, the reduced Gibbs entropy is equal to the minimum number of yes/no questions that need to be answered in order to fully specify the microstate, given that we know the macrostate.>>]) Maxwell's demon can (hypothetically) reduce the thermodynamic entropy of a system by using information about the states of individual molecules; but, as Landauer (from 1961) and co-workers have shown, to function the demon himself must increase thermodynamic entropy in the process, by at least the amount of Shannon information he proposes to first acquire and store; and so the total entropy does not decrease (which resolves the paradox).
Soon, sinners will be called down the sawdust trail to the old fashioned mourner's bench. Info Thermo-D Revival looks to be breaking out! (And I see HSR got to you quickly.)kairosfocus
