Our Brain Plays Games on Us!

Would you consider yourself to be an intuitive thinker?
Here are some brain teasers that will put your thinking to the test.

1. You are a participant in a race. You overtake the second person. What position are you in?
The intuitive answer is "I am now the first." The answer of course is that if you overtake the one who is second, you take his place, and you are now second.
2. Mary´s father has five daughters. Their names are: 1. Nana, 2. Nene, 3. Nini, 4. Nono and ?? What is the name of the fifth daughter?
The intuitive response most people give is to look after-a-e-i-o- and go with Nunu. The correct answer is already given in the question--Mary.
3. A cup and teapot set costs \$110. The teapot costs \$100 more than the cup. How much is the cup?
The intuitive response is \$110 - \$100 = \$10. The correct answer is \$5.
4. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
Your first response is probably to take a shortcut, and to divide the final answer by half. That leads you to twenty-four days. But that’s wrong. The correct solution is forty-seven days.
Get all four correct? Great job! Odds are your brain tried to force you to accept the wrong (fast) answers first, though, right?
That's a result of cognitive bias--the inherent thinking errors that we make in processing information.
Daniel Kahneman, who was the first psychologist to win the Nobel Prize in Economics (2002), explains why an intuitive reaction is not always the best.
In his groundbreaking book “Thinking: Fast and Slow,” Kahneman discusses intuitive (fast) and rational (slow) thinking. He shows us how an intuitive reaction could lead to problems and what the limitations are of our common sense.
So here is the "Kahneman Rule of Thumb."

It is safe to use your intuitive or "fast" thinking if:
• The issue is simple;
• You have seen an issue like this many times before and resolved it successfully;
• The cost of being wrong is low and the consequences are acceptable.
We recommend that you step back and use Kepner-Tregoe's Clear Thinking approach if:
• Issues are complex and the solution is not obvious;
• You have not seen an issue like this before. For example, a new machine falters and existing procedures and protocols are not bringing the solution;
• The cost of being wrong is high and the consequences unacceptable. For example, the machine stops, which significantly impairs the operation.
Ready for one last brain teaser?
Here's a final, "tricky math" puzzle just for fun:
Note: This riddle must be done in your head only -- do NOT write it down.

40;
1000;
30;
1000;
20;
1000;
and 10.
What is the new total?
Did you get 5,000? The actual answer is 4,100. The decimal sequence confuses our brain, which always jumps to the highest decimals (100s instead of 10s).
And here's a great video called "Brain Tricks: This is How Your Brain Works," produced by asapscience.
Have a great, clear thinking day!
