How do I tell what somebody is collecting?
Exposures are the loud half and almost everyone reads them. The quiet half is absence: if the threes and nines are all over the table and no sevens have appeared all game, somebody is holding sevens. Reading what is missing is the read that separates a good player from a careful one.

Exposures are the loud half
An exposure is the most honest thing at the table. It tells you what section of the card somebody is in, roughly how far along they are, and which tiles have permanently left circulation. Two or three exposures on one rack is a clock, and you should be watching it.
The mistake is stopping there. Exposures only appear when a player claims a discard, so a whole class of hand, and every careful player who is not calling yet, stays invisible to a reader who only looks at what is face up.
Absence is the read most players never make
Watch what is not in the discards. Over a hand, tiles flow steadily out of thirteen racks and onto the table, and the ones that never arrive are not random. If the threes and the nines have shown up repeatedly and the sevens have never appeared, four people are not independently ignoring sevens. Somebody is sitting on them.
This is harder than reading exposures because you are noticing an absence, and absences do not announce themselves. It gets much easier if you are already in the habit of watching discards go by rather than only watching your own rack. And it is worth the effort precisely because so few players do it: an opponent who has exposed nothing believes they are invisible, and against most tables they are right.
Two jokers in an early exposure is a warning
Read it twice over. It says that player is committed early, which is the ordinary meaning. It also says there are now two jokers sitting on the table that anyone holding the right natural tile can come and redeem, which makes that rack a destination for the rest of the hand.
So it changes two decisions at once. You should be more careful about what you feed that player, and you should be looking at whether you are holding the natural tile that turns one of those jokers into yours.
People are readable too, over a session
You cannot see anyone's rack, but you can absolutely learn a player. Some lock onto a hand immediately and never move. Some stay fluid for a long time. Some will push a hand with a hole in it right to the last tile, and some fold the moment anything tightens. All four of those are plannable once you know which is sitting across from you.
One caution. A player's style shifts as they improve, sometimes quite quickly, and a read you formed six months ago may be describing somebody who no longer exists. Hold it loosely, and keep watching.
Name the hand from the table
Exposure Detective gives you the discards and the exposures and asks you to name what somebody is quietly building. It is this skill, isolated and drilled.
