Self-Investigation
Overview
Self-investigation refers to the activity in which individuals or small groups collect, analyze, and interpret information on their own, without the help of external experts or institutions. This phenomenon has emerged rapidly in the 21st century due to advances in digital technology and improved information accessibility, and is utilized in various fields such as citizen science, personal data management, and self-diagnosis. Unlike traditional research methodologies, self-investigation is characterized by the subject being both the investigator and the object, which raises objectivity and ethical issues as major points of discussion.

Historical Background
The roots of self-investigation can be found in the DIY (Do It Yourself) movement of the late 20th century and the democratization of information in the Web 2.0 era of the 2000s. Initially, it appeared in the form of 'self-health management,' where individuals sought health information on their own, and later, the spread of genetic testing kits (e.g., 23andMe) made personal genome analysis possible. Since the 2010s, the proliferation of smartphones and wearable devices has led to the 'Quantified Self' movement, where individuals routinely collect biometric data.
Main Types
1. Health Self-Investigation: Activities where individuals measure blood pressure, blood sugar, heart rate, etc., using smart devices, or predict diseases through online symptom checkers. The use of self-diagnosis kits surged during the COVID-19 pandemic, popularizing this type.
2. Data Self-Investigation: The act of individuals analyzing their own social media usage records, location information, consumption patterns, etc., to enhance self-understanding. This has become more active since the enforcement of GDPR, which strengthened the right to access personal data.
3. Environmental Self-Investigation: Activities where citizens monitor their surrounding environment using air quality monitors, water testing kits, etc. This sometimes combines with environmental movements to influence government policies.
4. Legal Self-Investigation: The phenomenon of 'self-representation,' where individuals search for legal information and proceed with litigation on their own. In the United States, statistics show that about 70% of family court cases proceed without a lawyer.
Advantages and Limitations
Advantages:
- Cost reduction: Information can be obtained without the cost of hiring experts
- Time efficiency: Immediate investigation possible when needed
- Personalization: Collection of information optimized for one's own situation
- Empowerment: Strengthening individual decision-making power by resolving information asymmetry
Limitations:
- Information quality issues: Risk of exposure to misinformation or misleading data
- Interpretation errors: Drawing incorrect conclusions due to lack of expertise
- Ethical issues: Inadequate personal data protection, consent procedures, etc.
- Legal responsibility: Medical accidents due to incorrect self-diagnosis, etc.
Methodology
Self-investigation generally follows these steps:
1. Problem Definition: Setting the purpose and scope of the investigation
2. Data Collection: Utilizing public databases, APIs, sensors, surveys, etc.
3. Analysis: Using statistical tools (Excel, Python, R) or AI-based analysis platforms
4. Interpretation: Understanding the results in one's own context
5. Action: Making decisions based on the investigation results
Latest Trends
As of 2024-2025, self-investigation is rapidly evolving in combination with AI technology. In particular, 'AI-assisted self-investigation' using generative AI (e.g., ChatGPT, Gemini) has become common, with increasing cases of individuals delegating complex data analysis or legal document review to AI. For example, 'AI health coach' services, where individuals input their health data into AI to create personalized diet or exercise plans, are spreading.
Additionally, with the implementation of regulations such as the European Union's AI Act, demands for transparency and reliability of self-investigation tools are increasing. In 2025, 'Self-Investigation Ethical Guidelines' are expected to be announced in several countries, and in the medical field in particular, the 'patient-driven care' model, where self-diagnosis results are shared with doctors, is becoming standardized.
In South Korea, a pilot project linking self-investigation data with the public healthcare system has been underway since 2024 as part of the 'Personal Health Record (PHR) Activation Policy.' Furthermore, cases where environmental self-investigation data is used in government policy-making through citizen science projects (e.g., 'Citizen Air Quality Monitoring Network') are increasing.
