What is Fluid Intelligience? How does it relates to Investing Skill? | Investing Series

1. What is Fluid Intelligence?

Fluid intelligence is the capacity to reason, solve new problems, and adapt to novel situations without relying on previously acquired knowledge or skills.

It is the ability to think abstractly, identify patterns, and use logical reasoning to solve problems that are not based on past experience.

Think of it as your "on-the-spot" problem-solving ability. It's what you use when you're faced with a puzzle you've never seen before, trying to figure out a new game, or adapting to a new technology.

Fluid intelligence is often contrasted with crystallized intelligence, which is the knowledge and skills you have accumulated over a lifetime through education and experience.

While fluid intelligence tends to peak in young adulthood and may decline with age, crystallized intelligence generally increases as you get older.

How Does it Relate to Investing Skills?

Fluid intelligence plays a significant role in investment success, particularly in navigating the dynamic and often unpredictable world of finance. Here's how it relates to investment skills:

• Analyzing New Information: The financial markets are constantly changing. Fluid intelligence allows an investor to quickly grasp new market data, economic reports, and company news, and to integrate this information into their understanding of the market. It's the ability to see a new trend or a new type of financial product and understand its implications without a pre-existing mental framework.

• Problem-Solving and Strategic Thinking: Investing is essentially a series of complex problems to be solved. A high level of fluid intelligence helps an investor to develop and execute new strategies, analyze complex data sets, and make logical decisions in the face of uncertainty. For example, it could be used to devise a new asset allocation strategy or to figure out how a geopolitical event might affect a specific industry.

• Overcoming Behavioral Biases: Investing is fraught with psychological traps, such as the disposition effect (selling winners too early and holding on to losers) and framing effects. Fluid intelligence, coupled with other cognitive skills, can help an investor recognize these biases and make more rational decisions. It provides the capacity to step back from an emotional response and think logically about a course of action, even when faced with losses.

• Adapting to Market Changes: The financial landscape is not static. New technologies, regulations, and market structures emerge all the time. An investor with strong fluid intelligence can adapt their approach and strategies to these changes, rather than being stuck in outdated methods. It's the ability to be flexible in your thinking and to not rely solely on what has worked in the past.

While crystallized intelligence (e.g., knowledge of accounting principles, financial history, or specific market sectors) is also crucial for investing, fluid intelligence provides the raw processing power to use that knowledge effectively and to navigate the novel challenges that inevitably arise.

Some research even suggests that an individual's financial decision-making competence is a blend of both fluid and crystallized intelligence, as well as other factors like motivation and emotional regulation.

2. What is the difference between fluid intelligence and wisdom?

Fluid intelligence and wisdom, while both related to cognitive function, are distinct concepts. Think of it this way: fluid intelligence is a tool, while wisdom is the skilled application of multiple tools, including but not limited to intelligence, for a greater purpose.

Here's a breakdown of the key differences:

Fluid Intelligence

• Definition: The ability to reason and solve new problems without relying on prior knowledge. It's about mental agility, pattern recognition, and abstract thinking.

• Nature: A cognitive process. It's the "raw brain power" you use to tackle a novel puzzle or understand a new system.

• Development: It tends to peak in young adulthood and may decline with age. This is because it's closely tied to the speed and efficiency of the brain's processing.

• Scope: It is domain-general, meaning it can be applied to a wide variety of new situations, whether it's a logic puzzle, a new video game, or a complex math problem.

• Example: A 20-year-old quickly learning a new programming language or figuring out how to use a brand-new smartphone without reading the manual.

Wisdom

• Definition: A combination of knowledge, experience, good judgment, and a deeper understanding of life. It's the ability to apply one's intellect and knowledge to make thoughtful decisions that are not only beneficial to oneself but also to others and society.

• Nature: A more holistic, multidimensional virtue that involves cognitive, emotional, and social components. It's about how you use your intelligence, not just how much you have.

• Development: It is often associated with age and life experience. While not all older people are wise, a long life provides the opportunities for the reflection and learning from mistakes that are necessary to cultivate wisdom.

• Scope: It is often focused on the "fundamental pragmatics of life," such as dealing with complex human relationships, making difficult ethical decisions, and understanding the long-term consequences of actions.

• Example: An elderly judge, having seen countless cases and human stories, making a compassionate yet firm ruling that considers all parties and promotes the common good.

• 
  

In essence, fluid intelligence is the "how" of problem-solving—the mental horsepower.

Wisdom, on the other hand, is the "why" and "for whom"—it's the application of that horsepower with a larger, more ethical and reflective perspective.

You can be highly intelligent without being wise, but most conceptions of wisdom require a certain level of intelligence to be able to synthesize knowledge and reflect on experience.

3. How do I gain more fluid intelligence in investment?

Gaining fluid intelligence specifically for investment is about training your brain to think flexibly and logically about novel financial situations. It's less about memorizing market history (that's crystallized intelligence) and more about sharpening the cognitive tools you use to analyze and respond to new information.

Here are some strategies and exercises to help you develop the fluid intelligence necessary for better investment decisions:

1. Engage in "Brain Training" Activities

These exercises are designed to improve your working memory and abstract reasoning, which are core components of fluid intelligence.

• Logic Puzzles and Brain Teasers: Regular engagement with logic puzzles, riddles, Sudoku, and crosswords can train your brain to identify patterns and solve problems from different angles. These activities require you to hold multiple pieces of information in your mind and manipulate them to find a solution.

• Strategic Games: Play games that require strategic thinking and adapting to new situations, such as chess, poker, or other strategy-based board and video games. These games force you to anticipate your opponent's moves, plan several steps ahead, and adjust your strategy as circumstances change.

• Dual N-Back Training: This is a specific cognitive exercise that has been shown in some studies to improve fluid intelligence. It involves remembering a sequence of stimuli (e.g., visual and auditory) and responding when a current stimulus matches one from a specified number of steps back (the "n-back"). There are many apps and websites that offer this kind of training.

2. Diversify Your Learning and Thinking

Fluid intelligence is about making connections between different, seemingly unrelated ideas. Expanding your knowledge base beyond finance can help you see the bigger picture.

• Read Widely: Don't just read financial news and analysis. Read about history, technology, art, and science. The more diverse your knowledge, the more mental models you have to draw upon when a new and unexpected market event occurs. For example, understanding a historical technological revolution can give you a better framework for understanding the impact of a new one today.

• Learn a New Skill or Language: Learning a new skill that is very different from investing—like playing a musical instrument, learning to code, or taking up a new sport—creates new neural pathways and enhances your brain's plasticity, which is a key factor in fluid intelligence.

3. Practice Analytical and Critical Thinking

Applying these skills directly to your investment process is crucial.

• Analyze Opposing Viewpoints: When you read a bullish report on a stock, actively seek out a bearish counter-argument. Force yourself to understand the logic of the opposing side. This trains you to consider multiple possibilities and avoids confirmation bias, a common psychological trap for investors.

• Conduct "Pre-Mortem" Analysis: Before making a major investment, imagine that a year has passed and the investment has failed miserably. Write down all the reasons why it failed. This exercise, which draws on fluid intelligence to imagine future scenarios, helps you identify potential risks and weaknesses you might have otherwise overlooked.

• Break Down Complex Problems: When faced with a complex market problem, don't try to solve it all at once. Break it down into smaller, more manageable components. This is a fundamental aspect of fluid reasoning that allows you to tackle large-scale issues by focusing on their individual parts.

4. Optimize Your Brain's Health

Your cognitive abilities are directly tied to your physical and mental health.

• Regular Exercise: Physical activity, especially aerobic exercise, has been shown to improve cognitive function, including memory and processing speed.

• Mindfulness and Meditation: Practicing mindfulness can improve your ability to focus and regulate emotions, which are critical for making rational decisions under pressure.

• Adequate Sleep and Nutrition: A well-rested and well-nourished brain is a more effective brain. Ensure you are getting enough sleep and eating a balanced diet.

By consciously engaging in these activities, you can actively work to enhance your fluid intelligence, which in turn will improve your ability to adapt to new information, solve novel investment problems, and ultimately, make more effective and nimble decisions in the ever-changing world of finance.

Happy Investing! 😉
