Hyderabad: The Centre for Inquiry on Wednesday urged scientists not to conduct religious ceremonies in scientific laboratories. A recent survey by the Centre of Inquiry in association with a few other bodies discovered that a majority of the country’s scientists were “religious and even superstitious”.
The survey report was based on inputs from institutes all over the country, including Acharya Nagarjuna University, Andhra University, Visakhapatnam, Centre for DNA and Finger Printing and Diagnostics, Deccan College of Engineering and Technology, Kakatiya University, Maulana Azad National Institute of Technology and SV University from the state.
The survey said 44% of scientists believe in astrology while 41% believe in conducting ‘pujas’ before starting any major scientific activity. According to the members, scientists are setting a bad example to the rest of the country by believing in superstitions including vedic astrology. “There are many cases where scientists do pujas in their labs. This should not be permitted as there should be no observation of religious rites in any of the government institutions,” former CCMB director P M Bhargava said.
“A majority of the scientists said they believe in some super non-human power which protects all,” social activist Chandana Chakraborthy said. According to the founder member of the organisation, N Innaiah, many scientists believe in godmen too. Since the survey deals with scientists who come from different elite institutes in the country it is alarming to see these many people believing in superstitions.

If something goes wrong or if something does not turn out as expected, a typical Indian tendency is to ascribe those situations to ‘fate’. While ‘destiny’ is sometimes used as a counterpart to ‘fate’; in Kannada only one word describes the cause for the good and bad things, ‘vidhi’, which could be translated as ‘fate’.
People generally overlook numerous instances of things going right or otherwise but base their opinions on few incidents. However, these are the situations that matter them a lot. Though destiny does not matter much since the superstitions it develops do not necessarily harm the person or the society. But fate can have negative impact on person’s psyche, confidence and motivation. The superstitions that the person develops to get over the bad luck can be detrimental to him or the society. A question of interest would be ‘why does fate strike a person?’
A surest answer would be person expects something in a situation with too many ‘random experiments’. Let’s consider a situation.
Everyday, you take an auto to your office. Let us say you catch an auto at
A common person, even with a misconception of 0.7 probability as 100% availability, wouldn’t have fallen for a concept like ‘fate’ if atleast 70% of his ‘emergency situations’ have occurred as expected. A rarity. What is wrong? Simple. He has overlooked one more random variable, emergency situation itself. I will call this as an ‘internal random variable’. A probability 0.7 has to be divided between normal situation and emergency situation. Let’s consider you have emergency situation once in five days. A probability of 0.2. So, what is the chance of you catching an auto in an emergency situation? I will call it as probability of destiny(Pdestiny) and is equal to 0.7 * 0.2 = 0.14. In other words, you have only 14% chances of catching an auto in an emergency situation. This is the case in most of the human expectations. Fate will always triumph.
The only way to get rid of this spell of fate is to make sure you have as few ‘external random variables’, that you can’t control, as possible in your life. Also increase the probability of your ‘internal random variables’. An easy example would be trying to do something. One or two attempts will result in very low probability. So number of attempts must be many. Of course, you can always accept the fact that your probability of success is very limited.
