Natural variation and decision making

Gambar
Imagine you are in your 9th grade. You scored 80%, everyone expected you to. The teacher praises you. Your friend scored 40% and the teacher scolds him. Next exam. You score 76%. Your friend gets 45%. What just happened? It is seemingly logical that praising you got you to slack off and lose your grade while your friend benefited after scolding. The thing is, while it appears that the teacher influenced the grades, such a fluctuation is likely to be a natural fluctuation. Plain and simple changes that depend on so many variables that they appear random to us.  There is a very high chance that the teacher's scolding and praising changed nothing. This is called the regression fallacy . It is based on a couple of things. One is to discount natural variation. These innocuous random and natural fluctuations are often underestimated. Two, erroneous attribution of events to a controllable cause. Natural variations and fluctuations are significant causes that we often underestimate Where w...

4 cognitive biases you should be aware of

Gambar
These cognitive biases could be spoiling your decisions with incorrect perception. Understanding cognitive biases and overcoming them lie at the heart of negotiations, risk-taking, investments, audience building, developing relationships, choosing a moral side, debating, increasing sales, proving a point, etc. This is an endless list. Basically, anything that needs attention, observation, decision making, and perspective, can be compromised because of cognitive biases. 4 cognitive biases you should overcome to think clearly ... Thinking mistakes that the brain makes unknowingly. Telling you that cognitive biases compromise your decisions is a rather grim story. True, but grim. So I've already written a piece on how to counter cognitive biases . Do read that article once you are done with this post. Let us dive right in. The confirmation bias: Perhaps the most significant and elusive of all biases. Consider the example of person XY being anxious about social situations. Such a perso...

8 powerful ways to overcome thinking errors and cognitive biases

Gambar
There are cognitive biases and thinking errors. Our brains have evolved to have tendencies that, sometimes, and unfortunately, lead to errors. Our perception is compromised, our decisions are based on wrong information, our reactions are based on wrong information. So often. These could be errors in how the brain absorbs information- interpreting conversations, reading articles, understanding behaviour, understanding motivations of others, rights & wrongs. The brain has evolved quick tendencies for a reason, but many of them may be out of context today. For example, jumping to conclusions such as - the food is toxic based on a colour may have been useful back in the day, you know a million years ago when we were all babies. These 'heuristics' lead to highlighting day to day information in unproductive ways. Especially when there are inherent tendencies about oneself or the others.  For example, if there is a tendency to be self-critical, you might interpret social cues in ...

Top 5 psychology channels on Youtube

Gambar
I love watching youtube videos. In this short article, I'll share 5 of the best video channels about psychology. Top 5 Psychology Channels on YouTube for beginners, enthusiasts, and professionals (2018) If you like psychology, you MUST watch these. I would personally vouch for them (not endorsed, oh how I wish, sigh). They are all engaging, fun, and informative. Each of these channels has creators who put in a crazy amount of effort into making quality content. 1. PBS BrainCraft Short simple videos with a fun animation style. Vanessa hill really makes her content accessible. BrainCraft videos are usually very specific and crisp. I find BrainCraft to be on the fun side of psychological sciences. The topics she chooses can very well become topics of conversation in real life; without the pretence of intellectual debating. Go without saying (if seen her videos), the content is based on empirical research but the content isn't a numerical overload. She focuses on the concepts and t...

Inquiry based learning in the 21st century

Gambar
A number of learning systems exist today. Educational psychologists, as well as allied psychology researchers from cognitive science labs and rehabilitation centres, have invested a lot of time in studying how people should learn effectively. Over 500,000 results: articles/books/discussions from researchgate.net show up via google search. That is a lot and that is just one database. So after a quick check on google trends - people have been searching for 'Inquiry-based learning' more and more over time. And, people search for it the most approximately during April and October. Intuitively, doesn't that coincide with semester end preparation? The point of this is that Inquiry-based learning has been acknowledged globally and is supported by evidence (lots below). It, of course, isn't a perfect system; criticisms at the end. Inquiry-based learning - A promising learning model for the 21st century Research on inquiry and discovery methods in teaching The goal of inquiry-ba...

The many Qs - quotients to quantify all things alive

Humans like measurements. They like measuring land, the weight of gold, their penis, their breasts, their wealth, their age, their skills, their whole life. That's just back in the day. We have now measured the size of an atom, the universe, their facebook likes. That's not enough, is it? Let us move to the reality of humans. We measure our everything and compare it with dogs and dolphins. Let's measure everything in the universe and brag about those numbers that make us look good. - A human.  The fascinating art of measuring the human IQ, EQ, HQ, SQ, EQ, SQ Doctors love measuring.
