Deep dives
The Power of Targeted Donations to Effective Charities
Donating to effective charities can save lives and greatly impact those in need. By focusing on charities with high impact and evidence-backed opportunities, donors can ensure their donations make a significant difference. GiveWell, a charitable organization, spends extensive time researching and directing funding to the most effective charities. Their research and recommendations are published for free, enabling informed decision-making for high-impact giving.
Improving Knowledge Work through Tools for Thought
Knowledge workers, such as professionals in various industries, should focus on deliberate practice to enhance productivity. Tools for thought, like evergreen notes and spaced repetition memory systems, can optimize knowledge accumulation and retention. Evergreen notes capture single concepts, allowing users to build a web of interconnected knowledge. Spaced repetition memory systems prompt users at intervals to remember facts, improving long-term memory. These tools, along with other practices, create an intellectual exoskeleton that enhances productivity and knowledge retention.
The Transformative Power of Thought Tools
Tools for thought have the potential to revolutionize the way we think and solve problems. Historical examples like the Hindu Arabic numerical system and modern tools like Adobe Photoshop showcase the impact of thought tools. These tools change the patterns of thought by introducing new concepts, methods, and perspectives. They enable new possibilities and facilitate complex thinking by providing powerful ways to manipulate and organize information. The mnemonic medium, which integrates retrieval practice in books, is an example of a modern thought tool that can enhance learning and memory retention.
Retrieval Practice and Creating Effective Prompts
Retrieval practice, a technique that challenges memory recall, can significantly improve knowledge retention. Creating effective prompts for spaced repetition memory systems is crucial to reinforcing memory and understanding. Good prompts should specify precisely what needs to be remembered, connect knowledge from different angles, and reflect on prompt effectiveness. Refining prompts and being critical of their impact is essential for optimizing retrieval practice. While writing prompts is beneficial, finding the right balance of efficiency and processing is key.
The Importance of Joyful and Contextual Learning
When using memory systems and other augmentations for work, it is important to maintain a sense of joy and avoid turning tasks into burdens. Memory systems should be a means of connecting with inspiring ideas, practicing learning, and shaping the kind of learners we want to be. The danger lies in feeling obligated and turning the process into a chore. While there are challenges in reconciling this advice with classroom use, for professional knowledge workers, keeping the learning process joyful is essential.
Tools for Creating Prompts and Enhancing Memory Systems
There are various tools available for creating prompts and enhancing memory systems. Unkey is an open-source space repetition tool that offers flexibility but requires careful usage. RemNote and Mochi are hybrid writing and space repetition tools that allow note-taking and spaced repetition simultaneously. SuperMemo is a more feature-rich option for Windows users. However, the core skill to master is giving oneself tasks in the future. The author mentions a research environment tool called Orbit, which aims to integrate spaced repetition into reading, but it is still under development.
The Process of Evergreen Note-Taking
The speaker describes their process of evergreen note-taking when engaging with non-fiction books. They begin by evaluating the book's relevance and readiness for further exploration. They quickly skim through less relevant sections and focus more on the sections related to their questions. Throughout the reading process, they extract important insights as spaced repetition prompts and highlight key sections. After the initial pass, they summarize their understanding of the book, extract, cluster, and connect the highlighted ideas into evergreen notes. This process allows for better retention, future reference, and identification of supporting evidence for existing evergreen notes.
The Integration of Spaced Repetition and Evergreen Notes
The speaker highlights the potential integration of spaced repetition and evergreen notes. While the specifics are still being explored, they mention extracting questions and prompts from evergreen notes during the reading process. By doing so, they can reinforce key insights, connect them to existing evergreen notes, and strengthen their understanding of the topic. However, they acknowledge that further refinement and exploration are required to optimize this integration effectively.
From language and writing to the Hindu-Arabic numeral system, computers and Adobe Photoshop, our species has a history of inventing tools for augmenting our own intelligence. But what comes next?
Andy Matuschak is a developer and designer. He helped build iOS at Apple, founded and led Khan Academy's R&D lab, and now works as an independent researcher investigating 'tools for thought' — that is, technologies that can transform human cognition and creativity.
