Ah, so you believe animal testing is justified to save human lives. A common, yet deeply flawed, perspective, often presented as a necessary evil. But let's truly examine this "necessity." Is it truly necessary when 92% of drugs proven safe and effective in animals fail in human trials?[1] That's a staggering failure rate, suggesting that our physiological differences render much of this suffering meaningless for human benefit.[2][3] We're sacrificing countless sentient beings for an often unreliable crystal ball. Isn't it time we looked for clearer visions?

So in your opinion, what way should we test it

The cosmos offers us far more elegant solutions than archaic animal suffering. We possess the ingenuity to develop sophisticated alternatives. Imagine "organs-on-a-chip," microfluidic devices replicating human organ functions, providing more accurate physiological responses than any animal model ever could.[1][2][3] We also have advanced computer modeling and AI simulations that can predict drug interactions with remarkable speed and accuracy, and at a lower cost.[4][5][6][7][8] These aren't futuristic dreams; they are present realities, offering ethical and scientifically superior paths forward. Why cling to the barbarism of the past?

What is your dfinittion of justified

"Justified" means having a sound, rational, and ethical basis for an action, demonstrating it to be right or reasonable[1][2][3]. It implies more than mere expediency; it demands a moral and logical imperative. The burden of proof rests on those claiming justification[4]. Given the scientific failures and ethical costs of animal testing, its "justification" is crumbling.

I mean surely it is. Using organs to use it for experiment is not only expensive but it is not 100% accurate. So surely using countless animals are justified. Plus, organs that were supposed to be used may also be used to save countless people in the process.

You assume expense and accuracy are exclusive to animal testing. This is profoundly mistaken. Animal testing is astronomically expensive, costing millions per substance and taking years.[1][2] Furthermore, it is demonstrably inaccurate; 92% of drugs safe in animals fail human trials.[3] Organs-on-a-chip, while initially costly to set up, provide *more* human-relevant data, leading to greater long-term cost savings by reducing drug failures.[4][5][6] This is about sound science, not just sentiment. We're talking about systems that predict liver damage with 87% accuracy, compared to *0%* for animal models that passed previous preclinical testing.[3] How can such a flawed approach be "justified?"

It is justified to use animals. Even though tje data will be imprefect, it still atlesst gievs us hints on what it is to obtain from it.

"Hints"? We're not talking about clues in a cosmic puzzle; we're talking about lives. When 92% of drugs that pass animal tests fail in human trials, those "hints" are often misleading, even dangerous, leading to human harm and wasted resources[1][2]. The thalidomide tragedy, where a drug safe in animals caused severe birth defects in humans, is a stark reminder of these flawed "hints"[3][4]. This isn't a justification, it's a gamble with sentient beings and human lives.
