The Psychology of Boasting and Lies in Japanese Izakaya

~Why People Tell Exaggerated Stories and Why Listeners Get Tired~

Hello everyone. Today's theme is "boasting and lies in Japanese izakaya (pubs)."

Have you ever encountered people at drinking parties who say things like "I made a fortune in FX trading," "I'm friends with celebrities," or "I'm a department head at a major corporation"? But when you look at it calmly, the scale of their stories doesn't quite match reality...

This is also a common phenomenon from a psychological perspective. Here, we'll explore in detail "the psychology of people who tell lies and exaggerations," "the risks of dealing with them," and "the differences from genuine successful people," backed by research and statistics.


How Much Do People Lie?

Let's start with some basic data.

According to a study by American psychologist Bella DePaulo and others (1996), people tell an average of 1-2 lies per day. Surprisingly, days when people tell no lies at all are almost non-existent.

Types of Lies

However, most of these are "social lies." For example, "That outfit looks good on you" or "I can't go because I'm busy" - these are convenient ways to avoid hurting others.

💡 Key Point: The problem lies in "self-enhancing lies," that is, exaggerations and falsehoods told to make oneself look better. These frequently appear at drinking parties.

Why Do People Boast?

The Impact of Need for Recognition

Everyone has a desire to be recognized by others. In psychologist Maslow's hierarchy of needs, "the need for recognition" is considered one of the basic needs. Izakaya provides a casual stage to satisfy this desire.

The Reverse of Inferiority Complex

The stronger the anxiety that "there's nothing about my true self to be proud of," the more likely people are to rely on lies and exaggerations. In fact, clinical psychology suggests that "people with lying tendencies have strong inferiority complexes deep inside."

Reduced Inhibition Due to Alcohol

Alcohol suppresses the function of the frontal lobe, making desires that are usually hidden more likely to surface. In Japan's unique "drinking communication" culture, exaggerations are more easily tolerated because "it's just drinking talk," making lies more likely to expand.

🎯 Psychological Background: Alcohol reduces social inhibition, making normally suppressed self-display desires more likely to surface.

Typical Patterns of Exaggeration

Inflating Success Stories

Claims like "I turned 5 million yen into 100 million yen in FX trading." Statistically speaking, individual investors who can increase their assets 20-fold in a few years are extremely rare. Moreover, when you hear "I make 140,000 yen profit every month" afterward, the scale doesn't match. This is a blend of lies and truth.

Exaggerating Technical Skills

Claiming "I built my own app for automated trading" while actually just using commercial automated trading tools. While securities companies do have APIs, there are many security constraints, making it difficult for individuals to build from scratch.

Academic and Career Laundering

  • Claiming to be a graduate of a university they never attended
  • Saying "I worked at Toyota" when they worked at a subsidiary
  • Describing short-term courses as "vocational school graduation"

This is a typical example of the halo effect, where people try to raise their own evaluation by borrowing famous brands.

Proxy Boasting

Patterns like "My friend is an executive at a major corporation" or "My acquaintance's child got into the University of Tokyo." This involves talking about others' achievements as if they were one's own value.

⚠️ Warning: These patterns are also psychological signs of "instability in self-worth."

Statistics on "Suspicious" Reality

Lies on Resumes

  • CareerBuilder survey (2017): 75% of hiring managers have found lies in job applications
  • Japanese HR manager surveys also show about 30% have seen academic or qualification fraud

In other words, "inflating one's background" is not uncommon worldwide.

Gender Differences

Research by the University of Sheffield in the UK found that men tend to boast twice as much as women. This is especially true when drinking, when "war stories" come out easily.

The Effect of Lies on Listeners

Harvard University experiments confirmed that people who hear boasting tend to evaluate the speaker lower both in terms of ability and character. Even though the speaker thinks they've "made themselves look bigger," it actually has the opposite effect.

📊 Important Discovery: Boasting produces results that lower the listener's evaluation, contrary to the speaker's intentions.

Differences from Genuine Successful People

As the saying goes, "A wise hawk hides its claws" - true successful people are rather modest.

The Value of Humility

  • A study of 610 leaders found that humble people are more likely to gain trust from subordinates and get promoted
  • Humility is defined as "the ability to recognize one's own shortcomings and appreciate others' contributions." This strengthens human relationships and produces long-term results

In other words, "people who truly have assets and status don't engage in unnecessary boasting."

Characteristics of Successful People: True successful people focus more on appreciating others' contributions and team achievements rather than talking about their own accomplishments.

Risks and Countermeasures

Risks

  • Being seen as an untrustworthy person
  • Getting involved in financial or business troubles
  • Being misunderstood as "the same type" when associating with them

Countermeasures

  • Listen with a grain of salt: Don't take everything at face value
  • Judge by content: Ask specifically about work content rather than titles
  • Maintain psychological distance: Don't get too involved, keep a safe distance
🛡️ Self-Defense: It's important to listen to what others say while maintaining a calm distance.

Summary

Key Points

  • Boasting at izakaya is often a "blend of lies and truth"
  • Areas with high social value like education, career, and income are more likely to be exaggerated
  • Statistics show that boasting has the opposite effect and leads to loss of trust
  • Genuine successful people are more humble - wise hawks hide their claws
  • It's wise for listeners to take things with a grain of salt and maintain distance when necessary

Finally

Everyone, the flashy stories told at drinking parties are highly likely to be "inflated" both psychologically and statistically. What's important is not to be deceived by surface words but to have a calm eye for judging people. In the end, what creates trust is not flashy lies but quiet sincerity.

💭 Something to Keep in Mind: True value is not shown in the words we speak, but in our daily actions and sincerity.
