Evaluating the ROI of Information

文章探讨了信息消费的分类,包括仅作娱乐的琐事、无实际作用的自我满足式学习以及能产生实际效果的有效信息,并强调了信息媒介对学习效果的影响。

🎯信息可分为琐事、精神自慰式学习和有效信息。琐事仅具娱乐价值,精神自慰式学习虽有学习快感但无实际用处,有效信息则对个人产生可衡量的影响。

📱信息媒介比来源更重要。如阅读是主动媒介,能让大脑认为内容重要;而电视、视频等被动媒介易让人陷入无需思考的状态,影响学习和记忆效果。

👨‍👦作者以与父亲交流的不同主题为例,说明不同媒介和主题下获取的信息效果不同。如关于跑步的交流能获得有效信息,而某些关于个人理财的交流则被视为琐事。

🌐21世纪信息泛滥,被动媒介制造出一个缺乏连贯性和意义的世界,人们需为无用信息创造看似有用的情境,如填字游戏、鸡尾酒会等。

After consuming new information, it can be considered:


While stimulating myself with new information all day long (which I imagine many people do), it can be easy to fool myself into thinking that I’m making progress towards a goal.

The first principle is that you must not fool yourself—and you are the easiest person to fool. — Richard Feynman

But with this retrospective framework, I’m able to categorize and evaluate the ROI of information to see if it had a positive impact on me. Then I can selectively learn from what I personally deem to be effective information.

The medium is more important than the source

This framework is useful when applied across two dimensions: the source of information (e.g., family members, professors, content creators, etc), and the medium used to consume information (e.g., conversations, lectures, videos, etc).

I’ve noticed the medium in which I choose to learn something has a greater impact on the ROI than the source of the content itself.[2]

Some mediums promote active or passive consumption depending on the effort involved to process information. Reading, which I consider to be an active medium since the words won’t read themselves, often signals to my brain that the content I’m consuming is important and worth remembering. As Ian Leslie states in his book Curious:

We confuse the practice of [learning] with ease of access to information and forget that real [learning] requires the exercise of effort.

As I’ve written before, I’m not a huge fan of television or videos. I consider them to be passive mediums because they can just keep playing—I’m never forced to pause and critically think about its content. I previously highlighted research that showed:

Following prolonged [television or video sessions], the viewer develops a strange mix of physiological signs of high and low attention. Eyes stay focused, the body is still and directed towards the screen, but learning and memory drop to lower levels than when not [watching television or a video].

An Example

My father is an excellent source of effective information depending on the subject and the medium we use to communicate.


When I talk with him about running (he’s a marathon runner), I’m able to extract effective information and put it into use immediately. Whereas the running books he recommends make me feel motivated in the moment, but they don’t change my behavior and therefore I classify them as mental masturbation.

With personal finance, I’ve had enough conversations with my father to know that I don’t absorb much from our talks (Roth 401K vs Traditional 401K vs IRA—ugh, it’s too much to keep track of in my head). Because the conversations are fun but ultimately don’t change my behavior, I consider them trivia. Whereas the finance books he has recommended (The Simple Path to Wealth and The Millionaire Next Door) were effective information that helped me design a personal finance plan.
 

A peek-a-boo world of trivia

The passive mediums collectively manufacture what Neil Postman calls a “peek-a-boo world” in his book Amusing Ourselves to Death.

[Radio, film, TV, and now videos on the internet, together they call into being] a peek-a-boo world, where now this event, now that, pops into view for a moment, then vanishes again. It is a world without much coherence or sense… It is also endlessly entertaining.

With the flood of available information in the 21st century, it’s left me feeling numb in trying to achieve my goals. There are so many opportunities to get distracted by trivia and mental masturbation. Postman elaborates on this by saying that:

People once sought information to manage the real contexts of their lives, now they had to invent contexts in which otherwise useless information might be put to some apparent use. The crossword puzzle is one such pseudo-context; the cocktail party is another; the radio quiz shows of the 1930’s and 1940’s and the modern television game show are still others; and the ultimate, perhaps, is the wildly successful “Trivial Pursuit.” In one form or another, each of these supplies an answer to the question, “What am I to do with all these disconnected facts?” And in one form or another, the answer is the same: Why not use them for diversion? for entertainment? to amuse yourself, in a game? It is the only use left for information with no genuine connection to our lives.

Novel information is fun and can lead to strange new connections when combined with my accumulated knowledge. So I’ll never outright say that trivia is bad, per se. But I’ll reiterate what I said from my previous post on Mental Masturbation about intentional learning:

If I want to accomplish anything significant in my lifetime, then I must be selective in what I choose to consume in the name of “learning”, lest I delude myself into being endlessly distracted by information that could be useful in the future…

    Mental Masturbation: consuming information under the pretense of wanting to learn something useful, but in reality I’m “getting myself off” by indulging in subjects I’m already well-versed in.
