There's a psychological phenomenon (don't remember it's proper name), that the most attention is given to the beginning and to the end of a linearly ordered data (list, text, etc.).
This doesn't appear efficient though:
To get a better idea of the data, one should instead look into the middle of it. This way you get a better chance of not being bored immediately and learning something right away.
Moreover, I suppose offsetting cognitive biases in general is desirable.
