Multiple Thought Reflections are cumulative, each will double the amount of cards drawn. Thus, if you cast Divination with one of these in play, you draw four cards. If you have two Thoyght Reflections you would draw eight. Each replacement effect only modifies an action once, but they do it in sequence if there are more than one.
In the official rulings for this card (under the "Details" tag) it says this is the case.

5/1/2008 The effects of multiple Thought Reflections are cumulative. For example, if you have three Thought Reflections on the battlefield, you'll draw eight times the original number of cards.
Hope this helps.

Try this with Teferi's Puzzle Box and a Spellbook effect. Your hand size doubles and adds 2 every draw step. Combine it with Jace's Erasure for very effective milling or try any other "when you draw a card" effect. You can mill yourself with this combo so once your hand size is half your deck return one of the combo pieces to your hand or destroy it (preferably Thought Reflections).

Good card, if you have a plan for playing it cheap. Otherwise not really worthwhile.

I don't know why you think cumulative means additive. The effects stack on top of each other, thus cumulative. If you would draw 1 card, instead draw 2 cards. Since you're drawing 2 cards with 1 TR out, the second TR would make you draw a second card for each of those 2 cards, meaning you'd draw 4. With a third TR out, you'd draw a second card for each of those 4 cards, making you draw 8. Cumulative has nothing to do with being additive or multiplicative here - if it was not cumulative, it would mean that the most you could draw would be 2 cards per draw step, even with 4 TR out. The ruling makes perfect sense.

It's expensive, sure, but there are many ways to drop enchantments into play for free, such as Lost Auramancers, Gate to the Æther, Show and Tell, etc.. Consider this: If you play a Show and Tell on turn 3 with a Spellbook in play, you essentially have four cards every upkeep. Put a Bulwark, Cowed by Wisdom, and/or Solitary Confinement and you're on your way to a fairly fun discard/draw combo deck. Don't forget the Reminisces and you're doing well.
All cards have value, even the ones that are just awful. Card advantage is often much more valuable than it first seems.

actualy greyhour, having 3 out for....let me think...ONE TURN would be better than four Ancestral Recalls. :p
4 Recalls= 12 cards
3 of this = Draw a card on your turn; x2 =2; x2=4; x2 =8.
Ok, fine, so 4 Recalls, vs. 3 of this for one turn is ONLY 12 cards to 8.
Still. You can't do math. This thing scales FAST. REALLY FREAKING FAST. With Affinity for Artifact?!?!
Are you planning to use this shit with SKULLCLAMP or something?!?!!?? Shut. Up. Just shut, go home.
DESIGN all the cards you want, but you will never ever make a Development team. Ever. Anything you'd make would have to cost a billion mana.
