Logical Reasoning

Many people think that IQ tests are written to trick people however the reality is that tests are written to evaluate your ability to use logical reasoning. Logical reasoning is a repeatable process you use to come to a conclusion or answer to a proposed problem.

Logical reasoning can take direct routes or use indirect logic to find the answer to a problem. Many reasoning techniques are valid however it is important that you use the correct sequence of statements to prove or solve a particular problem.

For example, if I say I have 10 black balls in a bag and I also say there are a total of 20 balls in the bag, can I say that there are 10 white balls also in the bag ? You cannot, you can only say with certainty that there are 20 balls. Can I say there are more than 10 black balls ? No, you cannot say with certainty however you can say it is possible.

Jack and Jill have red and black hair respectively and go to the Children's School of Nursey Rhymes. Can I say that Jack is more that 3 feet tall ? No unless I say that all Red haired children that go to the Children's School of Nursey Rhymes are over 3 foot tall. The problem has several key pieces of information with the 'school' statement allowing the connection of the different pieces of information.

Logical reasoning can be hard at first mainly because we are inititally the product of our environment and upbringing with a large amount of knowledge being provided to us facts to memorize in order to protect us from harm or for easy living. The oven is hot - do not touch or you will burn yourself. If you put water into a freezer it will turn to ice. It is only later in life that we understand that the removal of heat from the water causes a drop in temperature until it reaches freezing point.

Can logical reasoning be taught ? Yes it can however some people find it easier to than others. A few examples of logical reasoning can switch on that thinking mechanism in your brain and with practice you can get better and better. Logical reasoning is essential for certain careers and professions such as science, mathematics, engineering, programming and medicine.

The trick with some IQ quizzes and tests is that often the information, assumptions and facts are not presented in the logical sequence to solve a problem. The skill for a problem solver is assembling the problem facts into the right order so you can draw conclusions or calculation addition information in order to solve the problem at hand.
