What this course teaches you to do

• Can name one official advisory service in Japan and in another country, relevant to a specific type of problem.
• Can, before consulting an expert, independently verify whether the service is free or paid and whose interests the expert represents.

Lessons (8)

1. Start with "Who wrote it?" — Applying primary and secondary sources to everyday information"Who, when, and on what basis?" When reading a secondary source, keep its potential for distortion in mind, and draw your conclusions only after returning to the primary source.
2. Use public institutions through four gateways — statistics, laws and regulations, the central bank, and consultationFor numbers, statistics; for rules, legal texts; for the system, central bank explanations; for problems, consultation. There are four entry points.
3. Map of Consultation Services (Japan) — Different Doors for Different Problems188, #9110, the Financial Services Agency, Nenkin Dial, and Houterasu. There are five doors. They do not necessarily solve the problem themselves; some services are there to provide guidance.
4. Map of where to get help (other countries) — Common principles, different points of entryIn the US, it's the FTC and CFPB; in the UK, Report Fraud; in the EU, your national ECC. Although their structures differ, the principle of first asking "Have you contacted the other party?" is common to all.
5. How to use an expert — Free or paid, and whose side they are onFree or paid? Who pays? Is there an institution that publishes a list of qualifications and disciplinary actions? These three things, before you take a seat.
6. Discerning Information — Advertisements, Affiliates, Social Media, and Generated TextWho paid? If it is marked as an "advertisement," read it with the understanding that it may be exaggerated. If not, verify it yourself.
7. Four things to verify yourself — time point, unit, denominator, and source.Time point, unit, denominator, and source. Normalize numbers with different denominators before comparing them, and keep a record of the formula used for normalization.
8. Official Information Also Changes — The Habit of Noting the Date You Read ItOfficial pages also change. Note the date you read phone numbers and opening hours, and check again on the day you use them.
