Extracting only the 'useful laws' makes work and life faster—77 amazing laws worth knowing (Business Psychology)

Introduction🚪

☑️ Don't start until the day before the deadline, and end up rushing
☑️ Can't stop researching, and get tired before actually doing the work (satisfied with just gathering information)
☑️ TODOs are too big, and can't take the first step
☑️ Leave tasks that take 10 minutes untouched for days for some reason
☑️ Meetings are long, but nothing gets decided
☑️ Having too many choices makes it harder to choose
☑️ Can't change from the safe 'usual way'
☑️ The day ends with only 'urgent' tasks finished, rather than important ones
☑️ Afraid of opposition, so can't even start a small experiment
☑️ The day melts away while thinking 'I'll do it when I feel motivated'

These all seem to fall under behavioral patterns like 'status quo bias,' 'Parkinson's Law,' 'planning fallacy,' 'Emmett's Law,' and 'the paradox of choice.' I picked up this book thinking I wanted to know if there were laws to mitigate these.

✅ People who want to acquire useful information for both business and private life

Learnings and insights gained from reading🤔

• Observation: Many 'laws' serve as a 'stepping stone' to organize behavior into smaller pieces. Rather than difficult theories, start with one move.

• Interpretation: I am the type who aims for perfection and ends up unable to move. That's why restriction rules like 'only the first 25 minutes' or 'meetings with 6 people for 30 minutes' were effective.

• Proposal (Today's step): (1) Start the most difficult task of the day for only 25 minutes / (2) Declare that meetings will be 6 people, 30 minutes, and 3 points to decide / (3) Arrange proposals in the order of AIDMA.

Impressive phrases/scenes in my own way☝️

🔴 Experience is the best teacher. 70-20-10 forces the design of the 'field.' Instead of learning, let's create an environment where we try things first.

Knowledge is the first step in everything. Rather than becoming a know-how collector and ending up not taking action, it is better to gain some knowledge and then take the first step!

🔴 Delaying the start creates invisible interest. Start with the difficult tasks and pay off your psychological debt first.

Procrastination is 'mental debt'. I've experienced how 25 minutes on the hardest task makes your mind feel lighter.

🔴 The success of a meeting is determined by the number of people and the time. 6 people, 30 minutes, 3 things to decide. That is enough.

Just by deciding the rules in advance, discussions won't get scattered.

🔴 Conformity can be both a driving force and a shackle. Build support from 16% to 30%, while always checking for counter-evidence.

I've created a map to gradually expand the 'circle of agreement'. The idea of handling opposing opinions with an FAQ is practical.

🔴 Small abnormalities are trailers for major accidents. Embed '1-line log -> weekly correction' into your system.

Just leaving a single line about a near-miss reduces recurrence. A mechanism that is easy to continue.

Put the knowledge you've gained into practice immediately 🤼‍♀️

Mini-procedure: Do the difficult work first (Emmett)

1. Roughly divide your work into A/B/C (C = the most difficult).

2. Write down the '**1-line goal for C**' (e.g., identify 3 important points in the contract).

3. Work on C for only 25 minutes (timer is okay).

4. Before stopping, write down the 'next step' in one line and interrupt.

5. After that, process B -> A all at once. The next morning, resume C from the 'next step' you wrote down.

Mini-procedure: Meetings that don't expand in time (Parkinson)

1. Participation is 6 people or less.

2. One sentence for the purpose and 3 things to decide should be shared at the beginning.

3. Fixed at 30 minutes. Use the first 20 minutes to exhaust all discussion points.

4. In the last 5 minutes, verbally confirm the 'decisions, responsibilities, and deadlines'.

5. Immediately share a one-page summary of the meeting.

Mini-procedure: Getting internal proposals approved using AIDMA

• A (Attention): Show loss amounts or opportunities on a single page.

• I (Interest): Demonstrate that it 'really works' using case studies and data.

• D (Desire): Express the benefits of time, cost, and satisfaction in a formula-like way.

• M (Memory): Have them encounter it repeatedly through weekly reports or demos.

• A (Action): Clearly state the MVP (plan to start small), structure, and deadlines.

Checklist: 3 points for simplification (Mayer)

• □ Did you show the overall picture in one diagram?

• □ Can you state what you want to convey most in 140 characters?

• □ Did you move detailed information to the appendix
  ? *Example: News commentary is fine as 'Headline -> 3 Key Points -> Supplementary Info'.

Checklist: Increasing trust (Windsor/Reciprocity)

• □ Third-party testimonials (other departments/customers) included?

• □ Did you provide information or support first?

• □ Did you write facts and opinions separately?
  *Example: For product pages, place 'Client logos + short reviews' at the very top.

Mini-procedure: Expanding the circle of support (Critical Mass)

1. Create a list of 10 influential people.

2. Create a space for early experience, and create one winning case study.

3. Announce 16% support within the company, and expand the circle to 30%.

4. Summarize reasons for opposition in an FAQ and explain them repeatedly.

Mini-procedure: Designing add-on purchases (Tension Reduction)

1. After the main product is decided, offer related, low-cost, high-frequency items.

2. Show limited offers near the cart or checkout.

3. Keep the reason for the addition short (reduces effort, provides protection, improves experience).

Checklist: Early extinguishing of risks (Heinrich's Law)

• □ Everyone records small abnormalities in a one-line log

• □ Once a week, organize causes and recurrence prevention separately

• □ Keep photos/screenshots of completed corrections

Once again, I want these people to read this🤗

✅ People who have long meetings but struggle to reach conclusions:

Meetings will be short and decisive by using the format of number of people, time, and '3 points to decide' (faster decision-making).

✅ People who want to fix their procrastination habits:

Just by working on the most difficult task for 25 minutes, the mental burden decreases (faster start).

✅ People who lack confidence in how they communicate (internal proposals, materials):

By rearranging AIDMA, the reader's understanding improves (easier to get approval).

✅ People who want to acquire information useful for both business and private life:

There are many 'small tips' that work for meetings, studying, shopping, and housework, so you can use them in your daily life immediately (high versatility).

A quick look at some concepts and laws that caught my eye☝️

• Emmett’s Law

  1. Meaning: The time and energy spent worrying and procrastinating before doing something is often more wasteful than actually doing it. An empirical rule that procrastination has a high 'psychological cost'.Square+1
     When to use: For tasks that feel heavy, start small, such as 'just work on it for 25 minutes,' to create momentum.
     Note: This is an 'empirical rule,' not a scientific law. Keep in mind that it is not a universal solution.

• Parkinson’s Law

  1. Meaning: 'Work expands to fill the time available for its completion.' It means that if the deadline is long, the work will drag on.Cambridge Dictionary
     When to use: Set meetings to a fixed 30 minutes, and for document creation, decide on the 'completion criteria' first and put it in a time box.
     Note: Zero margin leads to quality degradation. Secure a buffer separately.

• Mayer’s Principles of Multimedia Learning

  1. Meaning: 12 practical rules for teaching with images, text, and audio (e.g., removing unnecessary information = coherence, emphasizing important points = signaling, avoiding redundancy between narration and text = redundancy, etc.). Guidelines for improving learning effectiveness.will-links.jp
     When to use: Creating slides or training materials. Design for 'instant understanding' using one image and three key points.
     Caution: Trying to satisfy all of them at once can lead to over-optimization. Start with the three core principles (remove unnecessary info, emphasize, and spatial contiguity).

• Windsor Effect

  1. Meaning: The psychological phenomenon where 'third-party recommendations or reputations' are more persuasive than the person's own self-promotion.Cross Marketing
     When to use: Include 'recommendations from other departments, customer testimonials, or external data' in proposals, landing pages, and internal approval requests.
     Caution: Staged or overly dramatic presentations can have the opposite effect. Clearly distinguish between sources and facts.

• Critical Mass

  1. Meaning: The 'critical point' where adoption begins to run on its own. A state where, once the number of adopters reaches a certain level, it spreads like a snowball effect.Wikipedia
     When to use: When introducing a new tool in the office, have an 'influential minority' experience it, create a winning case study, and expand the circle from 16% to 30%.SolvInnov
     Caution: It is not just about the number of people, but the 'quality (reputation/role)' that is key. Who you ignite is important.Wikipedia

• Tension Reduction

  1. Meaning: The psychology where, after a large purchase, the desire to 'reduce anxiety' kicks in, making it easier to choose related additional purchases or warranties.note
     When to use: Present 'low-cost, compatible' accessories near the cart and justify the purchase anxiety (effort, protection, improved experience) with a short sentence.
     Caution: Hard selling damages trust. Focus entirely on reinforcing the 'feeling of having made a good purchase'.

• Heinrich’s Law

  1. Meaning: An empirical rule in safety engineering stating that behind one major accident, there are 29 minor injuries and 300 near-misses. It emphasizes the importance of early correction.Studocu
     When to use: Report small anomalies to everyone via a 'one-line log' → decide on one cause and one preventive measure weekly → close with evidence (photos/screenshots).
     Note: The ratio is a guideline. Don't get too hung up on the numbers; instead, cultivate a culture of 'nipping small buds in the bud'.

• Growth is '70-20-10'
  Key point: 70% comes from practical work, 20% from guidance, and 10% from learning.
  Reason: Experiential learning has the highest transfer rate.
  Implication: Design 'opportunities to do' such as transfers or new projects, and verify learning in the field.

Finally 🙂‍↕️

There were many things I thought, 'I learned this before' in training or other books, and that is precisely why I reaffirmed that they are useful.
'70-20-10', 'Emmett', 'Parkinson', 'AIDMA', 'Sho-Chiku-Bai' (Pine-Bamboo-Plum), and so on.
It is packed with ideas that can be tested in practice.
It might even be worth carrying around as a pocket handbook so you can incorporate them according to the situation 😁
I intend to keep '70-20-10' and 'Emmett's Law' in mind at all times as I act.
There is plenty of other useful information here. Please pick it up and try to improve your real life.

I hope this helps those who read this note improve their lives, both in business and in private 😊
Your support through comments and 'likes' will encourage me in creating future articles 😆

I also run a blog called 'An Interpretation by a Fool'.
http://www.minami-shaanashi.com/
In addition to book introductions, I am also steadily publishing my efforts in household budget management, stock investment, dieting, and health management from an ordinary person's perspective.
The concept is 'As an ordinary person among the masses, I will improve my current situation in my own ordinary way'.
If you'd like, please come take a look. Support and comments are very welcome! 🙌

In closing, I will add a passage from my bible,
'THE ALMANACK OF NAVAL RAVIKANT'.
