Shall we talk about deductive reasoning?

Imagine that you woke up in the morning and went to the kitchen. You turned on the light switch, but the light didn't come on. But you saw that all the other lights in the house were working. You immediately thought, "Oh... the light bulb in this kitchen must have burned out." That's how we use related facts to come to a specific conclusion, which is simply what we call `Deductive Reasoning`. We do this many times a day without even realizing it. Today we are going to talk about this amazing ability.

Simply put, what is Deductive Reasoning?

`Deductive Reasoning` is a mental process that we use to make decisions and solve problems. Strictly speaking, it is something related to our intellect. In this method, we reach a specific conclusion based on one or more general ideas that we accept as true.

It's like building something out of Lego pieces. The ideas we have in our minds that we accept as "this is true" are our Lego pieces. By putting those pieces together, we build a conclusion that we think is new and true.

Although we all use this every day, this is actually a bit of a complicated process.

• Researchers study this to understand how people learn, think, and make decisions.
• People like psychologists and neurologists also consider this when measuring a person's cognitive abilities .
• Some employment agencies may measure this ability in tests they conduct before hiring employees.

Your ability to think logically in this way depends entirely on a healthy brain. Some diseases and injuries that affect the brain can reduce this ability. This can make it difficult to understand information and make decisions.

Shall we look at some more examples?

The most famous example of this comes from the Greek philosopher Aristotle.

• First fact: All people die. (This is a common truth that we all know).
• Second point: Socrates is a man. (This is also something we know).
• Conclusion: So, Socrates dies.

Got it? By combining two common facts we know, we have come to a definite conclusion.

Let's take the example of the light we talked about earlier.

• First thing: The light above this room doesn't work.
• Second point: When you turn on the switch, another light comes on (meaning it's not a problem with the current).
• Conclusion: So, there is something wrong with that non-working light (like the bulb is burnt out).

We use this method from simple things like that to solving complex problems.

How does our brain do this?

Neuroscientists are still figuring out exactly what happens inside the brain when we think logically in this way. However, it is widely accepted that the left frontal lobe of our brain is actively involved in this.

Research has shown that different parts of the frontal lobe are activated at different stages of this logical thinking process. This means that this is not something that happens all at once, but a process that occurs in several steps.

What medical conditions can affect this ability?

There are many medical conditions and other causes that can affect the frontal lobe of our brain and, through it, our ability to think logically. The table below lists some of them.

Does aging affect this?

Yes, it can have some effect. As we age, our bodies change, and so do our brains. For example, the frontal lobe of the brain can shrink a bit with age. This can affect mental processes like logical thinking. But this doesn't happen to everyone the same way.

How does a doctor detect conditions like this?

If a doctor suspects that you have a medical condition that is affecting your ability to think logically, they may order several tests to determine the exact cause. Not everyone will need all of these tests. Your doctor will decide which tests are needed based on your symptoms and condition.

What are the treatments for these conditions?

Treatment options depend on the underlying cause of your cognitive impairment. Your doctor will plan your treatment based on that cause. Here are some of the most commonly used treatments.

• Cognitive rehabilitation: This involves training in various strategies that help you perform daily tasks more easily, such as ways to organize things.
• Cognitive Behavioral Therapy (CBT): A talk-based treatment that helps with things like sleep problems and mood issues.
• Medication and psychotherapy: These two treatments are often used together for mental health problems.
• Occupational therapy: This therapy helps people overcome the physical, mental, and social challenges they face in daily life.
• Physical therapy: This treatment helps improve the body's movement and function.
• Speech and language therapy: Provides exercises and training to improve speech and language skills.

What can we do to keep our logical thinking skills sharp?

The best way to maintain your thinking power and reasoning ability is to take good care of your brain. There are a few simple lifestyle habits you can follow to do this.

• Limit alcohol: If you drink alcohol, limit it. The recommendation is to limit it to two units per day for men and one unit per day for women.
• Eat a good diet: Fill your plate with vegetables, fruits, legumes, lean proteins (fish, chicken, eggs), and good fats.
• Exercise your brain: Doing things like crossword puzzles, jigsaw puzzles, and word search games is a great way to keep your brain active. Learning something new is also a great exercise for your brain.
• Keep your body active: Daily exercise helps keep your entire body healthy, including your brain.
• Get enough sleep: Try to get at least 7-8 hours of good sleep every night. It is during sleep that the brain repairs itself.
• Protect the brain: You can protect the brain from accidents by wearing a seat belt when riding in a vehicle and wearing a helmet when playing sports or doing risky jobs.
• Avoid smoking: Smoking increases the risk of stroke. This directly affects brain function.

Ultimately, whenever you gather information, make a decision, or solve a problem, you are using this ability called `Deductive Reasoning.` It is a very important mental process that is managed by our brain. Keeping your brain healthy can help keep this ability sharp.
