Breaking the Myth of Personality Tests

 

 

 

 

 

 

 

This is Prithi, again, the fifth grader with another blog post.

Do you have this interest or that? That means that you are one type or the other.

Most of our lives are based on questions like this: personality tests. What people don’t realize is that most personality tests are based on general information. Take the video (which I linked to the last phrase). Everyone gets the same results, even when they seemed very personal. Take this horoscope for example:

Pisces: Travel or short trips will probably be your best outlet. You are exceptional at presenting your ideas. Don’t overspend on friends or children.

Aries: Your ability to deal with others will help you in getting the support you need. Short trips will prove to be more fruitful than you imagined. Your home environment may be hectic, which could result in emotional upset if you aren’t well organized.

 

Taurus: Difficulties with female members of your family may result in estrangement’s. You may be offered opportunities that will result in a higher earning potential. Rewards for past good deeds will be yours.

 

Gemini: Deceit with coworkers is apparent. Your ability to put a deal together will surprise others. This will not be the time to give too much to your children.

Cancer: Your professional attitude will not go unnoticed. You should sit down with someone you trust and work out a budget that will enable you to save a little extra. Tempers will mount if you are too pushy at work.

 

Leo: You are best to put your efforts into redecorating or inviting friends over. Look into alternatives that would better suit both your needs. Overexertion and negligence will be your worst enemies.

 

Virgo: You will be inclined to make unwise investment choices. You can learn a great deal more if you listen rather than rant and rave. You may have difficulties finishing projects you start.

 

Libra: Someone may be trying to pull the wool over your eyes. You won’t get the reaction you want from your mate today. Your ability to be practical in business will help.

 

Scorpio: You will be able to get to the bottom of things today. Consider a conservative investment that will stay solid when everything else goes sour. You will be ready to jump on anyone who gets in the way of your progress today.

 

Sagitarius: Get out and experience the spice of life. Use your creative abilities to come up with new ideas and directions. Someone may be trying to pull the wool over your eyes.

 

Capricorn: Changes in your home environment may cause friction. If you’ve been really busy, try to schedule some time to spend with loved ones. Don’t overdo it.

 

Aquarius: Your ability to come up with good solutions for problems related to work will no doubt help you in getting a promotion. Plan a trip to the country or take a drive to the beach. Problems with your partner are apparent.

Does this seem personal? Well, it’s not. I took the horoscopes and switched them around.

Another example of personality tests was emphasized in one of my previous blog posts. The Sorting Hat. The questions that are asked don’t define you. They just group the people up according to their answers, into four houses or sectors.

Remember, don’t believe in those personality tests. They make their money from you. You don’t rely on them; they rely on you.

 

 

Don’t Classify People by Magic

I am Prithi the 5th grader writing this article.

Whether you are a Gryffindor or Slytherin, you are not defined by the Sorting Hat.

I am an avid fan of Harry Potter: I read the books about 20 times each.

In the Harry Potter seriesall characters were classified by a hat as they enter Hogwarts. We were told that the hat decides which one of the four houses to place a student in, according to its reading of their values.

For people like myself, who want to continue the journey through the seven books, there is a website called pottermore.com. There exists a similar classification of  young witches and wizards on the site, pottermore. Instead of putting on a virtual Sorting Hat, we are asked a bunch of questions which are supposed to determine which house we would be in. This can be helpful, as the answers to the questions were based on our values, which can match up to those of Gryffindor, Hufflepuff, Slytherin, and Ravenclaw. This can also be very judgemental, because the questions are multiple choice, and the user has a different answer, so he or she picks the next best one, getting classified by the answer they don’t want to choose.

The same goes for the Divergent series. People are classified according to their aptitudes and values.

Across the board classification appears everywhere, such as

  1. Which movie are you?
  2. Which dessert are you?
  3. I hope that when I grow up, colleges and businesses that I want to join won’t do the same thing: classifying people by magic. Everyone should know that people are not defined by ten silly questions.

May the Likelihoods Be Mostly in Your Favor

This is Prithi, the fifth grader, with another blog post, on probability. This title was inspired by Effie Trinket, in the Hunger Games.

Let’s say you buy a lottery ticket.You either win or lose. You figure that the chances are 50-50. What you don’t understand is that the chances are not 50-50. But you may ask: Isn’t it like a coin toss? The answer is no.

The explanation:

Let’s say the lottery ticket you buy is numbered from one to twenty. On drawing night, they pick one of the twenty numbers, and if you bought that ticket, you win. Otherwise, you lose.

Here’s a sample space for this problem:

{lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, win}.

Only one out of the twenty options can win. Win or lose are the two states you may find yourself in, but you are more likely to lose than win. The lottery tickets that we buy are not numbered from one to twenty, but have six numbers, from one to forty-two. They don’t pick one number, but six to find the winner. That means the chances are {lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose…

, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose, lose…

Oh, I can’t put a win anywhere here, because the chances of losing keep on going}

This is how the math will work: 1/42*1/41*1/40*1/39*1/38*1/37, or 0.000000000264763.

Therefore, the next time you buy a lottery ticket, don’t figure your chances are 50-50, and always make sure the likelihoods are mostly in your favor.

Brands Convincing us to Part with our Money

I’m Prithi, the fifth grader, writing this post.

Nestle has pretty good branding skills, especially when it comes to popular products, of course, they take it to extremes sometimes. People want refreshments, but they want to be healthy. The bottled water industry is very popular these days, along with all those diets and health movements.

Nestle cleverly takes advantage of us, as we are more than willing to part with our money, after their advertisements. They want to increase their margin, as Nestle Water provide the least margin of all, out of Nestle’s repertoire.With their smart advertisements, such as this one, they make us feel as if life cannot go on without Nestle Pure Life bottled water.

But do you really know the difference between one bottled water and another, when we pay the premium price?

Simple Price-Value Math from Tesla

Tesla discontinued its $71,000 Model S 60D and replaced it with Model S 70D that comes with all-wheel drive.

Its next higher edition in Model S is Model S 85D that has 85KWh rating (hence longer range) than 70KWh rating of 70D. The 85D however does not come with all-wheel drive, you upgrade by paying $5000 more.

Here is how the price value map looks like among the options

tesla-pic.001Essentially

Additional 15KWh  –  AWD  = $6250

Additional 15KWh + AWD    = $12500

You do the math on how much additional value customers assign to each feature. Clearly Tesla has done the math.

Is the value perception of AWD same for someone decided on 70KWh version vs. one who prefers 80KWh?

 

Nestle’s Marketing Fallacies

Hi, this is Prithi, the fifth grader writing about a wide span of topics, but today my post is on a marketing error.

There is a common noodle soup snack in India called Maggi, made by Nestle. This new advertisement they made has one main messaging error. Watch it carefully, then speculate.

The big revealment:

Take a look at the nutritional content of Maggi. Why would mothers want to feed their children something with so much sodium and fat?

Furthermore, in the advertisement, it shows a girl wanting to be self-reliant, but she should have learned to cook from scratch and eat healthy . To open a pack of processed food, boil it in water, and call that self-reliance is ludicrous and an insult to women in general.
