How to Think Critically: 5 Powerful Techniques

How to Think Critically: 5 Powerful Techniques

Critical thinking is the art of filtering through information to reach an unbiased, logical decision that guides better thought and action. It can be learned through powerful techniques listed in this article.

Before you read further, it is important for you to know that critical thinking is a state of mind, not a tool or strategy.

If you are bogged down in the trivial day to day matters of your professional and personal life, learning skills to develop your ability to think critically can help you rise above these issues and focus your energies where they are needed – to solve problems and accomplish objectives.

It stands to reason that the better the learning techniques, the better critical thinking and reasoning will be. My experience in helping people grow means I know exactly what is needed to teach critical thinking (hint: it’s not just pondering over the problem).

There are 5 powerful techniques that form the base of critical thinking:

  1. Analytical thinking
  2. Communication
  3. Creativity
  4. Open-mindedness
  5. Problem-solving

Once you learn the techniques listed and start employing them in your daily life, you’ll quickly start to notice a change in the way you approach problems and consequently, how you resolve them too.

1. Analytical Thinking

Analytical thinking is the gathering and breaking down of information into small bites that help make sense of it.

To use it for critical thinking:

  • Be very clear on why you need the information. This is to recognize your limitations and employ foresight to overcome them.
  • Gather information from as many sources as you can: peers and experts, podcasts, relevant literature and any other place you can think of.
  • Rephrase questions multiple times to get different perspectives on data available and possibly arrive at different solutions.
  • Break down the data into factual subsets and relate each to the issue at hand.
  • Think on paper to make new connections. Write, doodle, make mind-maps or use spreadsheets. Data presented visually can help you make new connections make sense of emerging patterns.
  • Tidy up the workplace. Once data has been gathered, your workspace and your brain will both be cluttered with excess information. Neaten the physical space and clear your mind with meditation. The change in focus will help you view the information in a new light, potentially helping you reach newer, better conclusions.

2. Communication

Communication is a key technique for critical thinking as it gives you access to the thoughts of people around you.

Data can be communicated through audio and visual means and in many cases, through careful observation of body language:

  • Ask for different points of view and seek justification for the same thing. When you invest in the matter, you will be able to explore all options to reach the best solution.
  • Listening without interrupting and only asking questions or voicing concerns once the speaker is done helps you make better connections.
  • Be 100% focused on a verbal or written discussion, you can better hear/read the opinions of the people involved.
  • Paraphrase the speaker/writer’s point of view and ask for affirmation. This enables you to pay full attention and use the input to think critically.
  • In a meeting, subtle communication cues are given by the body language of fellow attendees. An imperceptible frown, a small nod, pencil tapping etc. will all give you clues to what they are really thinking, just in case their actions are not in sync with their words!
  • Active observation, where you are watching and listening intently helps you know what to make of the information that is being passed around. It gives you clues to the general opinion about the topic under discussion and opens up new possibilities.

The information you gather through such communication will be invaluable in thinking critically to arrive at a decision that is holistic and unbiased.

3. Creativity

Critical thinking is an art, and like any art form, its lifeblood is creativity. To really learn critical thinking, you need to include elements of creativity in the process!

  • Brainstorm with your team in an all-new location or work-shadow an industry expert to step out of your comfort zone. You could be surprised by the ideas that flow at a picnic or a game of billiards!
  • Gather data and tabulate it in the form of colorful, eye-catching charts, graphs and mind maps. The simple exercise makes your mind bring data together in different ways and presents them so multiple unique conclusions can be reached, giving you the flexibility to choose the best one.
  • Play brain games such as Sudoku or chess to appreciate how different factors can be manipulated to reach a preferred outcome. These games help make connections between previously disconnected nerves, giving your brain the power to find multiple pathways to answering problems.
  • In a similar vein, you can forge new neural connections by learning a new skill, a new language or even a new recipe!

I break down creativity in my other article What is Creativity? We All Have It, and Need It. If you want to be good at critical thinking, you need to adopt creativity!

4. Open-Mindedness

It’s easy to say you’re open minded but is your mind really open?

To get an idea,

  • Be brutally honest about your strengths and weaknesses, and how these will impact the matter at hand.
  • Hear an opinion that conflicts with your own without forming a response before the opinion is fully voiced.
  • Acknowledge that there may be more than one approach to solving a problem and that they may all be right in some way.
  • Consider your true feelings when you will implement any required changes.
  • Disregard your long-held beliefs and assumptions and let go of habits.
  • Imagine the decision-making factors placed on weighing scales. Are they balanced?

Open-mindedness is a powerful technique for critical thinking. New possibilities can be uncovered, helping you resolve personal and professional matters in a manner that doesn’t frustrate you or alienate the other party.

5. Problem-Solving

Critical thinking is heavily dependent on problem-solving. An effective critical thinker will be a problem solver with the foresight to anticipate roadblocks and negative outcomes, and the experience and presence of mind to resolve them quickly and move on.

Advertising

One of the most effective problem-solving methodologies is the 5 Whys Analysis. Invented by Sakichi Toyoda, the founder of Toyota Motors in the 1950s, it has been used successfully by the automobile giant to get to the root cause of problems.

The idea behind this is simple: start with the end problem and keep asking why until you get to the root cause of it.

The general idea is that asking why 5 times from the effect is enough to get to the cause, hence the name. However, the methodology does not limit the questions to 5, and why can be asked as many times as need to peel away the layers until a satisfactory answer is reached.

To use the 5 Whys Analysis, start off by listing the problem and writing why in front of it. The next point in the list should be answer to the first why with another why in front of it. Continue answering the question asked above followed by a why until you’ve asked the question 5 times and answered it six times. 99% of the time, the last answer will be the root cause of the problem stated in the first point.

For example, consider the a commonly given scenario where a vehicle does not start.

  1. Vehicle will not start. Why?
  2. Battery is dead. Why?
  3. The alternator is not functioning. Why?
  4. The alternator belt has broken. Why?
  5. It was old and worn out. Why?
  6. The car is not maintained according to manufacturer’s recommendation.

By this example, it is clearly demonstrated that 5 whys were asked to reach the root cause of the problem.

The 5 techniques discussed here are important for effective critical thinking. When employed regularly they will become a habit and will definitely improve your critical thinking skills so you can get better at predicting and resolving issues that concern you and your environment.

Over the years, the 5 Whys Analysis has been adopted by millions to reach the root cause of their personal and professional problems. Industry giant Six Sigma has also incorporated the 5x Why Analysis in the Analyze phase of their DMAIC methodology.[1]

Final Thoughts

Is critical thinking a new-fangled notion? Not at all. Its history can be traced back to Socrates who questioned commonly held beliefs. This practice was carried forward by leading scholars and thinkers from different times such as Aristotle and Plato, Colet and Moore, Descartes, Galileo and Newton.[2]

Today’s world is dependent on critical thinking to resolve all sorts of issues. It is now indispensable for issues ranging from personal relationships to professional jobs and those involving the global community.

The 5 techniques discussed here are important for effective critical thinking. When employed regularly, they will become a habit and will definitely improve your critical thinking skills so you can get better at predicting and resolving issues that concern you and your environment.

5 Proven Memorization Techniques to Make the Most of Your Memory

5 Proven Memorization Techniques to Make the Most of Your Memory

Do you forget stuff every now and then? Are you trying to enhance your memory but not sure how?

All you need is the right memorization techniques to make the most of your memory.

The human brain is fascinating. More specifically, the vast interconnections within our mind. Mendel Kaelen compares the human brain to a hill covered in snow,

“Think of the brain as a hill covered in snow, and thoughts as sleds gliding down that hill. As one sled after another goes down the hill a small number of main trails will appear in the snow. And every time a new sled goes down, it will be drawn into preexisting trails, almost like a magnet. In time it becomes more and more difficulty to glide down the hill on any other path or in a different direction.”

The intent of Kaelen’s discussion is to think of new ways to temporarily flatten the snow. Kaelen remarked,

“The deeply worn trails disappear, and suddenly the sled can go in other directions, exploring new landscapes and, literally, creating new pathways.”

The idea here is to temporarily rewire your brain, or as Michael Pollan remarked in How to Change Your Mind,

“The power to shake the snow globe, disrupting unhealthy patterns of thought and creating a space of flexibility-entropy-in which more salubrious patterns and narratives have an opportunity to coalesce as the snow slowly settles.”

So, how can we rewire our brain allowing deeply worn connections to disappear and new connections to form? The answer is quite simple. We must change the way we store information in our mind.

    Let’s examine 5 specific memorization techniques that will change the way you think and remember information.

    1. Build a Memory Palace

      What is it?

      The method of loci[1] (aka memory palace) is a method of memory enhancement using visualizations with the use of spatial memory. It uses familiar information about your environment to quickly recall information. It is a method that was discussed by Cicero in an ancient dialogue called De Oratore.

      How to use it?

      Ron White discusses in How to Memorize Fast and Easily: Build a Memory Palace, that it’s essentially a room or building that you have memorized and you use locations in the room to store data. Ron informs us,

      “You memorize locations in a room and then you later go back to those locations to retrieve the data that you want to remember.”

      Example

      An easy 5-step example, in the form of a Wiki, can be found at Artofmemory.com. Let’s examine the the steps:

      • Step 1. Choose a place that you know well. For example, your house or office.
      • Step 2. Plan the route and pick specific locations in your route. For example, your front door, bathroom kitchen, etc.
      • Step 3. Decide what you want to memorize. For example, geography, list of items, answers for a test, etc.
      • Step 4. Place one or two items, with a mental image, and place them in your memory palace. Exaggerate your images. For example, use nudity or crazy images forcing it to stick in your mind.
      • Step 5. Make the image into a mnemonic.

      2. Mnemonic

        What is it?

        A mnemonic is a memory device that aids in retention and/or retrieval of information. Mnemonic systems are techniques consciously used to improve memory by helping us use information already stored in long-term memory to make memorization easier.[2]

        How to use it?

        Mnemonics make use of retrieval cues to encode information in our brain allowing for efficient storage and retrieval of the information. The trick is to learn how to easily create mnemonics. If you find that you struggle with creating your own, try the following website: Mnemonic Generator.

        Example

        I recently came across a video using mnemonics to memorize countries. Memorizing Countries using Mnemonics is a video created as an introduction to a class for using memory techniques to learn the names of countries on maps.

        I actively search for videos that provide enormous educational value, yet receive very little exposure. At the time of this writing, this video has received less than 4k views. Let’s examine the video.

        Goal: Create a mnemonic to memorize the countries in the Caribbean (just the countries you need to learn).

        Step 1. Looking at a map – write out each country (for which five were chosen).

        Cuba, Jamaica, Haiti, Dominican Republic, Puerto Rico.

        Step 2. Write the first letter of each country vertically.

        P

        Step 3. Create a sentence or phrase.

        Doing

        Push-ups

        Cubs just hate doing push-ups. (Cuba Jamaica Haiti Dominican Republic Puerto Rico)

        3. Mnemonic Peg System

          What is it?

          According to Artofmemory.com, a mnemonic peg system is a technique for memorizing lists and it works by memorizing a list of words that are easy to associate with the numbers they represent.[3] These objects are the pegs of the system.

          How to use it?

          The trick is to create a Number Rhyme System with each number having a rhyming mnemonic keyword.

          Example

          Let’s look at an example of a Number Rhyme System:[4]

          0 = hero

          1 = gun

          2 = shoe

          Advertising

          3 = tree

          4 = door

          5 = hive

          6 = sticks

          7 = heaven

          8 = gate

          9 = line

          Another technique like the Peg system is the Number Shape System.[5] Here you are assigning mnemonic images based on the shape of the number. Watch the following video for an example of this system: Number Shape System for Memorizing Numbers.

          4. Chunking

            What is it?

            Chunking is a way to remember large bits of information by chunking them into smaller pieces of information. We are more likely to then remember the information when we put the small pieces back together to see the entire picture.

            How to use it?

            In the video Chunking – A Learning Technique, we can see that there are several ways to chunk information.

            Example

            Let’s examine a simple example using a nine-digit number.

            Step 1. What is the number you are trying to remember?

            081127882

            Step 2. Cut the number into smaller pieces through chunking.

            Advertising

            081 – 127 – 882

            Let’s look at one more example from the same video.

            “Piano teachers will first demonstrate an entire song to students. They will then ask their students to practice one measure at a time. Once the part has been learned and the neural connections in the brain have been built, then students go on to the next measure. After all chunks have been played separately, they are combined until the entire piece is connected.”

            5. Transfer of Learning

              What is it?

              Transfer of learning is a way to learn something in one area and apply it in another. Authors of Thinking at Every Desk, Derek and Laura Cabrera inform us about the transfer of learning,

              “If a student has a high transfer skills, she can learn one thing and then teach herself 10, 50, or 100 additional things.”

              How to use it?

              There are two specific ways to use it:

              1. Vertical Transfer (aka Far Transfer). Think of learning something in grade school and applying it another grade or later in life.
              2. Horizontal Transfer (aka Near Transfer). Think of learning a concept in history and applying it in math.

              Example

              I provide a detailed step-by-step example for this technique in this article:

              Learn How to Learn: How to Understand and Connect Difficult Ideas Easily

              The Bottom Line

              The key to using the techniques discussed here is to remember that we must actively think about information.

              We cannot simply drill information into our brain through rote memorization. We must change the way we think about memorization. We must find a way to “shake the snow-globe” in our mind or flatten the snow so that we can create new learning paths.

              Or as Derek and Laura Cabrera point out, we must insert “Thinking” into the equation,

              “Information X Thinking = Knowledge”
