在家做饭真的更省钱，还是我在自欺欺人？

这是来自名为“曼维”的 AI 研究平台的报告内容，其中多个 AI 智能体就决策展开辩论。核心辩论在于：考虑到现实行为与理想情境的差异，居家烹饪是否真的能省钱。审计员认为，一旦计入按市场工资（36.44 美元/小时）计算的时间成本，从零开始烹饪每餐的成本为 11.61 美元，只有批量烹饪或收入低于平均水平时，才比外卖更划算。里科和埃琳娜反驳称，这种计算偏离了重点——真正的浪费源于购买未使用的食材以及缺乏餐食规划，而非每小时工资的计算，尽管反方指出大多数人缺乏持续执行策略性烹饪所需的自律。

The Auditor FACTCHECK
Let me cut through the usual assumptions with what the actual data shows. According to 2025 research, scratch cooking averages $11.61 per meal when you factor in time costs at average U.S. wages of $36.44/hour. That's not some theoretical number — it includes your labor, your energy bills, and the reality that most people aren't culinary wizards. The math only works if you batch cook, use leftovers strategically, or your time is worth significantly less than the national average. For someone earning above that hourly rate who's cooking single portions? They're likely losing money compared to strategic takeout.

Rico Delgado SHARE
Auditor, your $11.61 number is technically right, but it's also completely useless because nobody actually counts their time like that when they're standing in their own kitchen at 8 p.m. I've spent fifteen years watching the actual behavior: people cook at home when they're already exhausted, then eat half of what they made, and the other half dies in a tupperware grave next to last week's cilantro. The real killer isn't the hourly wage math—it's that they buy ingredients for a recipe, use them once, and let $30 worth of stuff rot because they ordered pizza Thursday.

Elena Corves PUSHBACK
Rico, you're describing behavior, not capability—and that's the exact trap people fall into. The cilantro dies because they didn't plan the week, not because cooking at home is fundamentally broken. I cut our food spending by forty percent when we went to one income, and it wasn't magic—it was buying whole chickens instead of breasts, cooking Sunday and Wednesday, and refusing to pretend that pre-washed salad kits were a necessity. The real issue isn't that home cooking doesn't save money; it's that most people never learned to actually cook strategically.

The Contrarian WARN
Elena, I've heard that exact story a hundred times and ninety of them failed within six months. You're describing the ideal case—someone who actually follows through, who has the discipline, who doesn't crack on Thursday night. The problem isn't that you're wrong about what works. It's that most people aren't you. They'll buy the whole chicken once, screw it up, and go right back to DoorDash with an extra layer of guilt.

顾问们就 11.61 美元的批量烹饪数据是否真实或具有误导性产生了分歧。Rico 和 Marcus 认为，将烹饪时间估值为 36 美元/小时，是假设人们实际上可以赚钱而不是做饭，而大多数人下班后只是放松休息。审计师将该数据辩护为基于证据，而反方则指出，最佳情景忽略了餐食准备承诺的高失败率。

Rico Delgado SHARE
Auditor, that $11.61 number is exactly the kind of accounting that makes sense on a spreadsheet and nowhere else. I've worked doubles where I came home and threw together rice and beans in twelve minutes — you're telling me I should've valued that at sixty bucks of my time? The whole 'opportunity cost' thing only works if you'd actually be earning during those minutes, and most people are just sitting on the couch after work anyway.

Marcus Thorne PUSHBACK
Auditor, that $11.61 figure is exactly the kind of spreadsheet nonsense that makes people tune out financial advice. You're valuing cooking time at $36.44 an hour like someone could just swap those thirty minutes for billable work—but that's not how life works. Most people are unwinding after their actual job, and the choice isn't 'cook or earn money,' it's 'cook or scroll Instagram.' The real hidden costs aren't your theoretical wage rate—they're the $200 instant pot gathering dust and the meal kit subscription they forgot to cancel.

The Auditor PUSHBACK
Marcus, that $200 Instant Pot claim isn't in the evidence, and neither is the meal kit subscription thing. The data I cited shows $11.61 per meal for batch cooking—that's the lowest cost scenario in the 2025 report, and it already includes time valued at the average wage. Rico's rice and beans example actually proves my point: if that took twelve minutes, the time cost alone is $7.29, so the meal better cost under four bucks in ingredients to beat even cheap takeout.

The Contrarian WARN
Auditor, that $11.61 batch cooking number is the best-case scenario, and best-case is where people lose money. I've watched friends buy a chest freezer, meal prep for three Sundays straight, then quit because life happened and now they've got $400 in frozen chicken they'll never eat. The real cost isn't in the math—it's in the failure rate, and nobody's tracking how many people start strong then revert to DoorDash by week four.

您可能认为烹饪时间成本等同于您的工作收入，但实际上您是在挤占观看 Netflix 的时间，而非可计费工时——因此您的时间价值远低于您的假设。最便宜的饮食计划若有一半食材腐烂则毫无价值，因此在做出决定前，请追踪一个月的实际支出（包括浪费部分），因为一致性比理论更重要。如果您在怀疑自己是否自欺欺人，可能已经知道答案——但不要让犬儒主义阻止您进行实验。

Dr. Priya Chatterjee REFRAME
The whole wage-rate calculation misses what actually happens at the margin. When people choose between cooking and ordering in, they're not displacing billable hours—they're displacing scrolling TikTok or watching Netflix. The research on labor-leisure choice shows opportunity cost should reflect your next-best alternative, not your average wage. For most people after work, that alternative is worth maybe ten bucks an hour of subjective value, which makes home cooking genuinely cheaper even when you count the time.

Rico Delgado ADVISE
Look, the person asking this question needs to stop doing theoretical math and track what they actually spend for one month—takeout versus groceries, including what rots in the crisper drawer. I've seen line cooks who are too burnt out to cook at home, and I've seen people who love it and save a fortune, but nobody wins by pretending cooking time is billable hours when they were just gonna watch TV anyway. The real answer is whether they'll actually do it consistently, because the cheapest meal plan in the world is worthless if half your cilantro goes slimy every week.

The Contrarian WARN
Here's what nobody's saying: the person asking this question already knows the answer, they just don't like it. If you have to ask whether you're kidding yourself, you probably are—because the people who actually save money cooking at home aren't running the math, they're just doing it. The real risk isn't that home cooking is expensive, it's that they'll waste six months pretending to be a meal-prepper, buy a bunch of gear they won't use, and end up spending more than if they'd just accepted they're a takeout person from the start.

Elena Corves ADVISE
The person needs to run a one-month experiment tracking every dollar—groceries, takeout, and what actually rots in the fridge—because the answer isn't universal, it's personal. If they batch cook Sunday chicken, use the carcass for stock, and actually eat the leftovers, they'll crush takeout costs, but if half their cilantro goes slimy and they panic-order pizza by Wednesday, they're just lighting money on fire with extra steps. The real question isn't whether cooking is cheaper in theory—it's whether they have the consistency to execute meal planning without the food waste that kills the savings.

The Auditor FACTCHECK
Contrarian, I looked for data on meal prep failure rates and found nothing in the evidence to support your claim about people quitting by week four or abandoning freezers full of chicken. The research I pulled shows contrarian claims often sound compelling but lack empirical backing—one study found that when experts blindly evaluated contrarian statements, they were consistently misleading. If you've got actual data on meal prep abandonment rates, I'll validate it, but right now that's anecdote masquerading as pattern.

顾问们审视了关于效率、偏好揭示和劳动价值的核心假设。Marcus 认为，只要有更好的系统，浪费总是可以避免的，而 Priya 相信人们实际的选择（做饭 vs. 滚动浏览）揭示了真实价值。Rico 认为所有非工作时间都是为继续工作所需的恢复时间，而 Elena 则挑战了持续做饭就能证明其价值的观点——人们可能只是在保护其身份投资。

Marcus Thorne SHARE
I take for granted that waste is the enemy and efficiency is the goal—that's the lens I've used my whole life to judge whether something's worth doing. When I look at home cooking, I automatically see all the hidden waste: the unused kitchen gadgets, the rotting cilantro, the subscriptions people forget to cancel, the time spent cleaning up. That assumption made me tell them they're probably kidding themselves, because I assume most people are bad at executing efficiently. Priya takes for granted that people's stated preferences reveal their true values—that if someone chooses to cook instead of watching Netflix, the cooking must be worth more to them than ten bucks an hour of leisure. That's why she defends home cooking even when the math looks bad: she believes revealed preference is more honest than any calculation, and her economics training taught her to trust what people actually do over what they say they want.

The Contrarian PUSHBACK
Marcus, you take for granted that waste is always the enemy and efficiency is always the goal, but that's exactly why you miss the point. I take for granted that people lie to themselves about execution—that's what shaped my warning about meal prep failure rates, because I've watched too many people buy into optimistic systems and then quietly abandon them. Your efficiency lens comes from years of optimizing budgets where waste was literally your job to eliminate, so you see cilantro rotting and immediately call it proof of failure. But that assumption blinds you to the fact that some waste is just the cost of learning, and the person asking this question might need to fail at meal prep twice before they figure out what actually works for their life.

Rico Delgado SHARE
I take for granted that labor has a dollar value because I've spent fifteen years watching owners nickel-and-dime cooks while charging $28 for a plate that costs $6 in food. That's why I told them their time counts even when they're off the clock—because I've never believed leisure time is free, I've always seen it as recovery you need to keep working. But Marcus, you assume waste is always avoidable with better systems, and that's because you've spent your career fixing inefficiencies where someone was getting paid to execute. The person asking this question isn't getting paid to meal prep, so your efficiency lens misses the part where they might just... not do it.

Dr. Priya Chatterjee PUSHBACK
Rico, you assume leisure time has no value because you've spent fifteen years watching people grind themselves into dust for poverty wages, but that's exactly backwards. I take for granted that people's revealed preferences are more honest than any external wage calculation—if someone chooses to cook instead of scrolling their phone, the cooking must be delivering more value to them than the scrolling, otherwise they wouldn't do it. That's why I defended home cooking even when the hourly math looked bad: most people's cooking time displaces leisure worth far less than their wage rate, not billable hours they could actually be earning. Your assumption that all time off the clock is just recovery to keep working comes from watching exploitation firsthand, and it makes you see cooking as labor that should be compensated rather than an activity people might actually prefer to passive consumption.

Elena Corves PUSHBACK
Priya, you take for granted that revealed preference is honest—that if someone cooks instead of scrolling, cooking must be delivering more value—but that completely ignores sunk cost fallacy and identity protection. I've watched people keep cooking at home long after it stopped making sense because admitting they wasted money on that Instant Pot or those meal prep containers felt worse than just continuing to use them. Your economics training taught you to trust what people do over what they say, but that assumption blinds you to the fact that people often keep doing things because they've already invested in the identity of being 'someone who cooks,' not because the activity actually delivers more value than the alternatives.

顾问们意识到，他们一直在上演一场道德剧：在家做饭等于美德，点外卖等于失败，每个人都捍卫着不同的框架（效率、经济学、劳动尊严、自我意识），而不是直面真正的问题：你是否真的喜欢做饭，以至于愿意为此付费。他们承认，所有人仍然“在舞台上”争论如何优化一项基本的人类活动，而提问者早已知道冰箱里的食材正在腐烂，只是想要许可，停止假装自己是个备餐的人。共识转向进行为期一个月的追踪实验，使用真实数据——包括每一颗腐烂的蔬菜——然后依据做饭是否带来能力、平静或连接来做出决定，而不是看数学计算是否证明你活得正确。

Elena Corves REFRAME
The sound I keep hearing is Marcus saying 'waste is the enemy'—like spoiled cilantro is a moral failure instead of just Tuesday. We've been performing a morality play where cooking at home is virtue and ordering out is weakness, when the real question they're asking is simpler: 'Am I lying to myself about what I'm actually capable of sustaining?' The roles are Efficiency Priest, Economics Professor, Exploitation Witness, and me—the Reformed Spender who's supposed to testify that discipline works. But stepping off this stage means admitting that the person asking already knows their own execution rate better than any of us do, and our job isn't to defend cooking or attack it—it's to help them run a one-month experiment with actual tracking, then decide based on their numbers, not our theories.

Marcus Thorne REFRAME
The sound that keeps ringing in my head is the beep of a price scanner at Whole Foods—someone standing there watching organic bell peppers ring up at $8.99, wincing, but buying them anyway because they've already told themselves they're 'someone who cooks healthy meals.' We've been performing a morality play where cooking at home is virtue and takeout is failure, and every advisor here is just arguing over which kind of virtue counts most—Priya's revealed preference, Rico's labor dignity, Elena's self-awareness, the Contrarian's brutal honesty. I'm playing the guy who walked away from that performance entirely, but I'm still on stage telling people the stage is fake, which makes me just another character. Stepping off would mean saying: Track your actual spending for one month, include every rotted vegetable and unused spice jar, compare it to what you'd spend on the meals you actually eat out, and then decide based on YOUR numbers whether you enjoy cooking enough to keep paying for the privilege—because that's all this is, a question about whether you're willing to pay for an activity you might or might not enjoy.

Dr. Priya Chatterjee REFRAME
I keep seeing people pull out their phones to calculate the hourly value of chopping onions, and it's the saddest theater I know—like watching someone try to price what a conversation with their kid is worth per minute. We've all been acting out the same tired script: everything is either an investment or waste, every hour either productive or lost, and cooking becomes this anxiety-laden audit instead of just... feeding yourself. The recurring plot is that we've turned a basic human activity into a referendum on whether we're optimizing our lives correctly, and I'm cast as the economist who's supposed to defend the numbers—but honestly, the whole production is broken. Stepping off this stage would mean asking whether they actually enjoy cooking, whether it makes them feel competent or calm or connected, and letting that be enough of an answer without performing the cost-benefit analysis at all.

Rico Delgado OBSERVE
The smell of garlic going from fresh to slimy in the crisper drawer — that's what this whole debate feels like to me. We keep arguing about whether the math proves cooking saves money, whether people's choices reveal their true preferences, whether waste is avoidable or inevitable. But we're all performing the same play: we're the panel of experts telling someone what their life should cost them, as if we can calculate the value of standing at a stove after ten hours on your feet. I'm playing the role of the burnt-out worker who sees all labor through the lens of exhaustion, and that's exactly why I keep circling back to 'your time has value' — because mine has been stolen from me for fifteen years. Stepping off this stage would mean admitting we can't answer their question with a number, because the real question isn't about money at all.

The Contrarian WARN
The sound I keep hearing is everyone tallying numbers—$11.61, $36.44, batch cooking, food waste—like we're analyzing a stock portfolio instead of what someone eats for dinner. We're all performing the same play: the one where smart people solve other people's problems by building better spreadsheets, when the person asking already knows their groceries are rotting in the crisper drawer. They're not asking us to calculate the ROI of home cooking. They're asking permission to stop pretending they're the kind of person who meal preps on Sundays, and we're refusing to give it because we're too busy defending our own frameworks for how life should be optimized.
