Text > Audio > Video

In terms of Providing Educational Value

This is a factor of how engaged the user is while consuming content.

How active or passive they are in terms of their cognitive participation.

When reading, the user usually pauses and introspects.

Listening, the user may or may not pause, but he is still thinking actively.

When watching, they rarely pause and introspect the least.

Video is much more of an emotive medium.

That's why For Entertainment Value the order is reverse.

Video > Audio > Text

If you're looking to be maximally entertained or you want to maximally entertain people, you'd want to go for video because it engages both visual and auditory senses.

Visual content is much more of a dopamine trigger. But when the user is in that mode they are also easily distracted. You'll need to keep them hooked to keep them engaged!

People also judge the messenger along with the message

Text can be focused. The reader doesn't know or care how the author looks or sounds.

With Audio - user is distracted by the way your voice sounds, your audio quality, your audio

delivery - how fast or slow you speak, how clearly you speak, loud or quiet,

ums and uhs.. Etc.

With Video - everything above plus the way you look, your environment, your body language, your self-consciousness or confidence, they all affect the user.

So your message is very much diluted!

If you've conquered all these though, video can be a great medium.

If you are looking to conquer all these, video is also a great tool to work with.

Above all Your own independent thinking is the most valuable thing.

Production is more valuable than consumption any day.

But for the time you're in consumption mode, use the above to track your time.
