Does Thinking About God Increase Our Willingness to Make Risky Decisions?



By Jalees Rehman


There are at least two ways of how the topic of trust in God is broached in Friday sermons that I have attended in the United States. Some imams lament the decrease of trust in God in the age of modernity. Instead of trusting God that He is looking out for the believers, modern day Muslims believe that they can control their destiny on their own without any Divine assistance. These imams see this lack of trust in God as a sign of weakening faith and an overall demise in piety. But in recent years, I have also heard an increasing number of sermons mentioning an important story from the Muslim tradition. In this story, Prophet Muhammad asked a Bedouin why he was leaving his camel untied and thus taking the risk that this valuable animal might wander off and disappear. When the Bedouin responded that he placed his trust in God who would ensure that the animal stayed put, the Prophet told him that he still needed to first tie up his camel and then place his trust in God. Sermons referring to this story admonish their audience to avoid the trap of fatalism. Just because you trust God does not mean that it obviates the need for rational and responsible action by each individual.


It is much easier for me to identify with the camel-tying camp because I find it rather challenging to take risks exclusively based on the trust in an inscrutable and minimally communicative entity. Both, believers and non-believers, take risks in personal matters such as finance or health. However, in my experience, many believers who make a risky financial decision or take a health risk by rejecting a medical treatment backed by strong scientific evidence tend to invoke the name of God when explaining why they took the risk. There is a sense that God is there to back them up and provide some security if the risky decision leads to a detrimental outcome. It would therefore not be far-fetched to conclude that invoking the name of God may increase risk-taking behavior, especially in people with firm religious beliefs. Nevertheless, psychological research in the past decades has suggested the opposite: Religiosity and reminders of God seem to be associated with a reduction in risk-taking behavior.


Daniella Kupor and her colleagues at Stanford University have recently published the paper “Anticipating Divine Protection? Reminders of God Can Increase Nonmoral Risk Taking ” which takes a new look at the link between invoking the name of God and risky behaviors. The researchers hypothesized that reminders of God may have opposite effects on varying types of risk-taking behavior. For example, risk-taking behavior that is deemed ‘immoral’ such as taking sexual risks or cheating may be suppressed by invoking God, whereas taking non-moral risks, such as making risky investments or sky-diving, might be increased because reminders of God provide a sense of security. According to Kupor and colleagues, it is important to classify the type of risky behavior in relation to how society perceives God’s approval or disapproval of the behavior. The researchers conducted a variety of experiments to test this hypothesis using online study participants.


One of the experiments involved running ads on a social media network and then assessing the rate of how often the social media users clicked on slightly different wordings of the ad texts. The researchers ran the ads 452,051 times on accounts registered to users over the age of 18 years residing in the United States. The participants either saw ads for non-moral risk-taking behavior (skydiving), moral risk-taking behavior (bribery) or a control behavior (playing video games) and each ad came either in a ‘God version’ or a standard version.







Bias and Spin



By Mark Crislip


We all construct our narrative based on our biases and spin the facts so that the narrative confirms our biases. Among other characteristics, what separates an SBM provider from a SCAM provider is realizing that biases are always active and apply to me as well as everyone else.


My biases are simple: I am skeptical that humans can reliably understand reality without assistance and the best source of assistance is science.


I have a job where the expectation is that I will change practice as information changes. How I practiced medicine 30 years ago is very different from how I practice it today. Still, I note it is harder and harder to change my approaches as I get older. I get more set in my ways and it takes more effort to change as new studies are published. Sometimes it seems almost physically difficult.


Again, it is expected that not only will I change my mind over time, as the sole ID doctor at my hospitals, I will be the one to lead the change. Imagine how much harder it would be to change your mind if you were committed to a universal truth such as those that are alleged to underlie reiki or chiropractic. Years committed to a pseudo-medicine probably renders changing one’s mind virtually impossible.


I will admit there is one bias I cannot fathom, the conspiracy/pharmaceutical shill world view. The idea that those of us concerned with pseudo-medicine are doing so because we are paid by big pharma is just so weird. There are a number of articles on Pubmed concerning medical conspiracies, but the search term “pharmaceutical shill’ yields nothing on either Google scholar or Pubmed. It is a bias that evidently has no research to help understand why people have that opinion. I suspect it is derived in part from the often-remarkable sums paid to some doctors to pimp medications to other doctors. But I can’t even find how common the belief is.


I can kind of understand why people practice and/or participate in the various SCAMs given my understanding of the various fallacies and dysfunctional ways the mind works. It is easy to see how both the practitioners and patients misjudge the efficacy of pseudo-medicine. We have evolved to survive reality, certainly not to understand it.









Earliest Human Species Possibly Found in Ethiopia

An ancient jawbone fragment is the oldest human fossil discovered yet, a bone potentially from a new species that reveals the human family may have arose a half million years earlier than previously thought, researchers say.


This find also sheds light on the kind of landscape where humans first originated, scientists added.


Although modern humans are the only human lineage alive today,other human species once roamed the Earth. These extinct lineages were members of the genus Homo just as modern humans are.


For decades, scientists have been searching Africa for signs of the earliest phases of the human family, during the shift from more apelikeAustralopithecus species to more human early Homo species. Until now, the earliest credible fossil evidence of the genus Homo was dated to about 2.3 million or 2.4 million years ago.

First ever photograph of light as a particle and a wave

By Science Daily


Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior.


Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle. The breakthrough work is published in Nature Communications.


When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this “photoelectric” effect by proposing that light — thought to only be a wave — is also a stream of particles. Even though a variety of experiments have successfully observed both the particle- and wave-like behaviors of light, they have never been able to observe both at the same time.


A new approach on a classic effect


A research team led by Fabrizio Carbone at EPFL has now carried out an experiment with a clever twist: using electrons to image light. The researchers have captured, for the first time ever, a single snapshot of light behaving simultaneously as both a wave and a stream of particles particle.





Deeper Ties to Corporate Cash for Doubtful Climate Researcher

For years, politicians wanting to block legislation on climate change have bolstered their arguments by pointing to the work of a handful of scientists who claim that greenhouse gases pose little risk to humanity.


One of the names they invoke most often is Wei-Hock Soon, known as Willie, a scientist at the Harvard-Smithsonian Center for Astrophysics who claims that variations in the sun’s energy can largely explain recent global warming. He has often appeared on conservative news programs, testified before Congress and in state capitals, and starred at conferences of people who deny the risks of global warming.


But newly released documents show the extent to which Dr. Soon’s work has been tied to funding he received from corporate interests.


He has accepted more than $1.2 million in money from the fossil-fuel industry over the last decade while failing to disclose that conflict of interest in most of his scientific papers. At least 11 papers he has published since 2008 omitted such a disclosure, and in at least eight of those cases, he appears to have violated ethical guidelines of the journals that published his work.

Big, bright quasar from ancient universe stuns scientists

Deep in the universe’s past, astronomers have discovered a luminous quasar powered by an enormous black hole that contains the mass of 12 billion suns. The incredibly bright object is ancient — shining when the universe was only 875 million years old — and way bigger than it should be for an object its age.


The unusual quasar, described Wednesday in the journal Nature, is the biggest and brightest one known to have formed within 1 billion years of the Big Bang. The find could cause researchers to alter their understanding of how such super-massive black holes form — and shed light (literally) on the conditions in the early universe.


The quasar, named J010013.02+280225.8, or J0100+2802 for short, is powered by a massive black hole that’s pulling in so much stuff that the material accelerating toward it produces an incredible amount of light. There are about 40 known quasars spotted within a billion years of the Big Bang, and they weigh in around a billion solar masses. Compared with its peers, this quasar is a monster — by far the biggest and the brightest.


“We were surprised,” said study coauthor Xiaohui Fan, an astronomer with the Steward Observatory at the University of Arizona in Tucson.

A prominent American blogger of Bangladeshi origin has been hacked to death with machetes by unidentified assailants in Dhaka, after he allegedly received threats from Islamists.


The body of Avijit Roy, founder of the Mukto-Mona (Free-mind) blog site – which champions liberal secular writing in the Muslim-majority nation – was found covered in blood after an attack that also left his wife critically wounded.


“He died as he was brought to the hospital. His wife was also seriously wounded. She has lost a finger,” local police chief Sirajul Islam said.


The couple were on a bicycle rickshaw, returning from a book fair, when two assailants stopped and dragged them on to the pavement before striking them with machetes, local media reported, citing witnesses.
