Dunning Kruger Effect

Dunning Kruger Effect
This is one of the most prolific psychological effects that you will notice in everyday life- once you know what to look for.


When somebody first begins to learn a topic, they typically underestimate its difficulty and wind up vastly over confident in their own abilities. Over time, however, this confidence begins to drop off as more knowledge is learned (awareness of depth and complication of topic). Confidence then eventually picks up again as true expertise is gained.
The implication is that the most confident people often know very little about a subject- in fact, they know so little that they don't even understand how complicated the matter really is.
The original study found a very interesting example concerning perceived and actual test scores among the participants.
To quote from the abstract:
Across four studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although test scores put them in the 12th percentile, they estimated themselves to be in the 62nd.
You can see from the above chart that those who scored the worst on the test had the greatest overconfidence (difference between perceived and actual scores).

Every Indian should know!!

Every Indian should know!! Electricity is available to us at our finger tips throughout the day(at least in cities). We curse the government & supply agencies even when there is power cut of 5 minutes, but most of us do not know the effort  & courageous work  of many electricians, who put their lives at risk so that we can enjoy luxuries of electricity 24-7. The transmission lines that transfer power are subjected to harsh environments such as lightning, storms, rain etc., and gets damaged. Repairing these lines needs to be done without cutting off the supply. People who have experienced shock will know how fatal electricity can be and in Indian houses this voltage is around 220 V. Now imagine a voltage of 800000 V and how fatal it can be, in order to provide continuous power supply, people are made to work at these live voltages. for more updates visit :  https://coolhacksfactsrv.blogspot.com/ Despite having protecti...

Do you how many combinations does Standard 3x3x3 Rubik’s cube has?

Image
Do you know think a Rubik’s cube is the most complicated mechanical puzzle ever invented?  You have no idea how complicated mechanical puzzles can be. A Standard 3x3x3 Rubik’s cube can have  43,252,003,274,489,856,00 0  combinations, but only 1 solution. To put this into perspective, if we have one Rubik’s cube for each possible combination, then all the cubes will cover the whole surface of 275 earth-sized planets. and among all of them, only 1 cube will be in perfectly solved state. But for some people, this was not complicated enough. they created 4x4x4 cubes, and also 5x5x5 cubes. A 4x4x4 cube has  7401196841564901869874093 974498574336000000000 combinations. If you have that many teaspoons of sugar, it will fill a sphere the size of the solar system 3.5 times over. a 5x5x5 Rubik’s cube has  2828709422777418565361803 3310715032829312773198567 2134721536000000000000000  combinations, this is close to number of atoms in the known unive...

Difference between MBps and Mbps

Image
Difference between MBps and Mbps :  One of the silliest things that most of the people around me don’t know, is the difference between Mbps and MBps. Look at the advertisements below:- Have you ever wondered whether you are getting the mentioned speed or not? You can see that the speed of downloading is mentioned in Mbps. In computer terms, b denotes a bit and B denotes a byte. Also, as everyone might know, 1 B yte = 8 b its Now, whenever you copy any file from computer to, say, pendrive, the speed will be measured in MB/s or MBps which is exactly 8 times faster than that of Mbps. Often these two are confused. If you are confused, take this example - If you have to download a file of 1MB in your computer and your net speed is 1Mbps, it won't take 1 second to download it. Instead it will take 8 seconds. So, whenever you see any advertisement of 100 Mbps net speed, don't be surprised. Divide that by 8 and then you will get the actual speed of the ...
