A question from a reader:
I feel that 99.99% of what I read I forget; that the words flit by and leave me mostly unchanged. I do occasionally see a line that touches me, but rarely.
Are you the same? What do you do to increase the amount you retain and use productively from your reading?
If there is any question that I feel qualified to answer, it is this one, because I have given this an almost ridiculous amount of thought and I have tried a number of relevant experiments.
I wrote this in the intro to my
masculine booklet:
Ideas are fun, and can occasionally be life-changing, but who we are and how we perceive and interact with the world is to an uncomfortable degree a product of the unconscious. Which is to say that “ideas,” at least the conscious sort, probably matter less than we think.
I consume ideas at a rate that would suggest that I believe they will take me somewhere. But it’s obvious, judging by personal history, that they rarely do. I think it would be wise to accept that ideas are unlikely to change us, and adjust our consumption accordingly... but then that is itself just another idea, and so is unlikely to change our behavior. Ugh.
Ideas do not seem to have much effect on us [me] in a moment-to-moment sort of way. For instance, I may read something that opens my eyes to the wonder of the Universe, but when I wake up the next morning, rather than thinking about how wondrous the Universe is, I am going to think about, per usual, how badly I need to pee. This is pretty much inevitable.
Ideas don’t so much change my perspective or my behavior, but there are some ways that they have a more lasting influence on me. In particular, I am often serendipitously
reminded of ideas in ways that can add some insight to a situation, add some depth to a thought or discussion, or just plain make things a little more interesting. This may not be the best example, but the other day I was out for a walk with my family and I looked up and saw a tiny little turd of a cloud. Which reminded me of something. I had heard a fascinating tidbit from
a Robert Krulwich segment awhile ago, and I raised it with my fam: “How much do you think that tiny little cloud up there weighs, in elephants?” Totally random, I know, but my family is used to these types of absurdities by now. They guessed, and they were, as expected, way off (except Mom, who did impressively well, but her guess was still off by a factor of two). The answer is 100 elephants. That’s interesting because it means that even what seem to be the daintiest of clouds still weigh a shit ton. That fact doesn’t do much to change my day-to-day perception of the world – I do not regularly perceive the vast weight hovering above me as a fact of the Universe – but when I am reminded of this fact, it’s interesting, and it made for a fun 30 seconds of conversation.
But really, Justin, what’s the use in holding such silly factoids in your brain? Fair question. A factoid about cloud weight in elephants is unlikely to add much to anyone’s life, but when you add up all the ideas I’ve assembled, it makes for a vast interconnected hodgepodge of stuff that may not so much affect who I am, but certainly affects what I consciously think about and what I talk about. In sum, it makes mental life more interesting. If you expect ideas to make you behave any differently or perceive the world any differently, you are bound to be disappointed, but you
can safely expect them to add some richness to your conscious thought and to your conversations. And that’s worth something.
Once we’ve accepted the limits of ideas, there are some things we can do to increase retention and influence (but again, this would require you to change your behavior, and I’m not optimistic about that happening). I squirm at the thought of this becoming a How To post, but what the hell:
First, recognize that context matters. People are more trusting of and more influenced by well-designed things. So, if you want ideas to penetrate your skull more deeply, a good start is to consume them from an aesthetic perfectionist. A TED Talk or a Werner Herzog documentary is going to be more successful in getting a point across in a meaningful way than a blog post or a home video. That should be obvious. (But you're reading this from a blog post, so maybe it's not.)
For more on the stickiness of ideas, I find
Dan and Chip Heath’s six principles to be a good start. But I think the important part comes not while consuming the ideas, but after. And for that I can recommend my own six principles (squirm):
#1. Write them down. There is a Big increase in retention from doing this. And handwriting seems to be more effective than typing.
#2. Question them. Or have others question them. I remember ideas much better when I have given them a mental colonoscopy.
#3. Re-visit them. This chart was huge in helping me understand how memory works:
(
Accompanying article in WIRED, 4/21/08)
My approach is to type up all the ideas from my notebook, typically about 3 months after they were originally written. I have also experimented with a program called
Mnemosyne that is like a flash-card program based on this memory principle. I found that it did increase retention, but not so much that I felt compelled to go out of my way to use the program.
#4. Explicitly connect them to other ideas. Based on my experience, this is significantly more effective than re-visiting. I do both, but I find that the ones that are explicitly connected to other ideas I remember more clearly and for a longer time.
This is a really important point that often goes overlooked:
Ideas need other ideas to tell them what they mean.
#5. Give them an intuitive place in your mind. Organize them into “chapters”. Memory champions do things like organize ideas into an imagined hotel or landscape.
#6. Explain it to someone. Bonus points if it’s someone who will scrutinize the idea. Double bonus points if it’s someone you respect.
These are the main factors that I have found to increase the clarity and longevity of my recall. And there are two big activities I have found that potently combine these components into a sort of steroid for memory muscles:
Blogging. I’d bet that anyone who blogs would agree that they remember the ideas they blog about much better than the ones they don’t. And it’s little wonder because blogging involves writing (#1), scrutinizing (#2 & #6), explaining (#6), and often connecting ideas (#4), and organizing them into subject areas (#5).
Idea Booklet-thingy. What I did with the masculine booklet was simple: Take all the ideas that I had written (#1) in my notebook over the past 3 months (#3), filter out the best ones (#2), scrutinize and re-word them to get to the heart of the point (#2 & #1), organize them into chapters (#5), organize them within chapters (#4), and then share them with a bunch of people I respect (#6, with bonus points).
Blogging works well as a memory aid, but the masculine booklet worked even surprisingly-er well-er. I just tested myself and I can’t quite recite the 446 ideas from memory – okay, I can’t at all – but if I am prompted by a related idea, I will be able to instantly tell you the idea, probably verbatim, along with at least a few surrounding ideas.
Once again, I think we have to ask why memory matters, because it’s not intuitively obvious. The best place that I’ve heard this discussed is in
Russ Robert’s podcast with Daniel Willingham. (The good part starts around 13 minutes.) The gist is that abstract reasoning is not just
thinking really hard but synthesizing things that are in memory and applying them from previous examples and looking for parallels and analogies and so on. In other words,
reasoning doesn’t work without lots of ideas in memory.
The next question is why abstract reasoning matters, and I’d rather not touch that subject right now. This post is already too long, so I’m ending it here.
