It is becoming common these days among people to preach dropping and picking up a book based on interest, but if you seriously want to express your opinion on the material or the person who has written that, at least try reading it completely before letting your preconceived notions get better of you.
Seen one way you would be misleading people who trust your opinion and perpetrating a lie that might destroy the credibility of the original creator. And in another way, this is just pure incompetence that is being rationalized as efficient mechanism to imbibe knowledge. Doesn't provide authority, doesn't allow for legitimacy, all it does is allows you to create an echo-chamber for yourself where you can engage in a pseudo-random verbal-diarrhea with like-minded people.
An example would be this:
"Witness here how salaried physicists are dismissing @stephen_wolfram Wolfram's automata BEFORE even hearing him Just as Freeman Dyson publicly dismissed A New Kind of Science c. 2002; it turned out that he did not read the book. & pple who refused to read it referred to Dyson!"

That said, it should be noted that switching books based on interest is not wrong, caution must be applied while talking about topics that you yourself have not completely gone through.
I'm convinced a lot of leprechauns or 'citogenesis' comes from people who don't read past the title or abstract but decide to cite it anyway as proof
—Email Exchange with GwernGwern describes this better than I ever can by comparing such second-hand partial information mongers to people who use leprechauns or 'citogenesis' based on reading the title/abstract of a paper. (See Below)
The only exception I have seen in this regard is Tyler Cowen, who advocates and practices this principle of dropping the books that you don't like…I go through five or ten books a day. And which parts of them I’ve read you can debate – maybe it washes out to be two or three books a day. Some good nights you can get through five whole books. The important thing is to be ruthless with the books that are not good. Just stop reading, put them down, usually throw them away, don’t give them away – if you give them away you could be doing harm to people.—Tyler Cowen, Tim Ferris Podcast. This is conflicting given his credibility as a prolific reader and an excellent knowledge worker. What remains to be known is if he authoritatively cites the sources that he has dropped?
Note: Remember any resource that you pick up is someone's sweat and blood. If you do not wish to read it, always make sure not to form opinions on it, or at least not to promulgate any partial information based on it. Always try to put yourself in such a situation and see how you'd have taken it — The Silver Rule.
“Do not do unto others as you would not have them do unto you.”
Most of the time our inability to read to completion has to do with association of the act of reading instead of the book that we are reading, context-switching can really help here.

…I generally read everything through if I goes past the abstract at all. I feel you can't really have an opinion if you haven't read the whole thing; if you don't read the whole thing, and you say anything about it, you are all too often perpetuating lies or half-truths. I'm convinced a lot of leprechauns or 'citogenesis' comes from people who don't read past the title or abstract but decide to cite it anyway as proof….

The important thing is to be ruthless with the books that are not good. Just stop reading, put them down, usually throw them away, don’t give them away – if you give them away you could be doing harm to people.
And my philosophy of reading is that no-one reads quickly. So someone once asked me “How long did it take you to read that book?” And I said, “Fifty-seven years.” I’m fifty-seven years old.
So the way you read well is just by reading a lot, and by reading a lot your whole life. And then when you go to read actual books you’re like “I know that, I know that, I know that,” and you keep on going, and you read much more quickly. And that’s really the way to read a lot. There are these compounding returns to being obsessed with reading, and starting young, and never stopping.
Sometimes readers just go on and on with blather, or with personal detail that has no relevance to the argument. Or there are just pages of terminology and it’s like, well, you might still give the book a chance, but you start turning the pages more rapidly. And you’re just waiting for some bit of meat, you’re like out there desperate, giving the author still a chance, and then at some point you’re like “No, sorry. ” Zap – throw it in the trash, on to the next one.
Most books are not half great and half horrible. And you should look at a few different parts of the book. But especially these days an author should be able to signal by putting some good stuff up front. Because people are less patient than they used to be. A nineteenth century book you need to give it more time, it may not get good until chapter three, but these days, my goodness – you can tell so much sometimes just from the font of a book. Like there are books with bad font – management books – and you’re like “Oh my God! It’s that font again!” And you just throw it out – you don’t have to read it at all…
The best reading is focused reading, when you’re trying to solve some kind of problem. So if I’m doing one of own podcasts with a guest, and then I’ll read or re-read everything the guest has written. Typically it’s a re-read because I have on guests I like, and if I like them I’ve already read a lot of their stuff. So you’re re-reading with an eye toward what is actually interesting about this person, and you learn much more that way than if you just randomly pick up books.
So I advocate reading books in cluster – the author can be the clustering factor, it can be the topic, it can be the historical period – but you really get into a person’s mind if you re-read everything they’ve done within the span of a few weeks or months, and then watch them on YouTube, and just try to think about and write out notes, “What am I going to ask them?” One of the very best ways to read is to have your own podcast.
You want to start with a problem or question when you’re reading. And again you want to read books together in groups, and you want one of the early books to make the whole thing real or emotionally vivid to you. If you travel to a place that’ll do it automatically, but if you’re not travelling you want the book to do it, so your early book choice is quite important. And then many areas – so take the case of Ancient Egypt … – I don’t know what’s the best book on Ancient Egypt, but I know there’s enough uncertainty about what went on in ancient Egypt that there’s probably not a clearly well-defined “Here’s the best book on ancient Egypt,” so you want to read ten or twenty of them and do a kind of cross-sectional mental econometrics and see which pieces start fitting together. And take it from that. So in so many areas it’s a mistake [to ask] “Oh, what’s the best book on X?” Rather you’re looking for some kind of portfolio of books on X.
My first recommendation would be fiction. Reading fiction is important to understand the cross-sectional variation in humanity, to understand how difficult generalisations can be, to just get a sense of how different social pieces fit together, and to get a sense of different historical eras – and plus, reading fiction is often just plain flat-out fun…
Every area you don’t given a damn about you probably should read at least one book in. Because the very best book in that area is superb, and you’re not going to know what it is. So if tennis is something you don’t know anything about, well, read Andre Agassi’s memoir. That’s a wonderful book. You don’t have to know about or care about tennis. And just go through other areas – gardening, dogs, turtles, whatever. Find the best book about dogs and read it, and the less you like dogs, actually, the better that book is going to be, because you are not sick of the topic.…
People don’t read enough, and I think as a society we’re under-investing in reading. People feel compelled to finish books they’ve started – that’s just a tax on your reading. Why would you do that to yourself? Imagine a world where any restaurant you tried you had to keep on going there for days or weeks, you’d hardly ever go out to eat.
Take reading seriously, develop a passion for it, and view it as part of your practice as a knowledge worker to get ahead, but along the way, having fun doing so.
