Variants to elicit
Focal: Discrete responses to small/large percentage changes in price of Impossible/Beyond Beef on amounts of [target products]
[Adjust to changes?]
If…
the price of “IB+” [variant: PBA] were to fall by 10% [variant: PRICE FALL%] (relative to its counterfactual price)
Evaluation of this operationalization
We can ask evaluators and others to state their beliefs on these, informed by the research (whether it reports elasticities or something else)
Reasonably understandable to non-economists
[PRICE FALL%] = 5%, 20%, and to price parity with avg. ground beef [TARGET PRODUCTS] = b. beef, c. pork, d. shrimp/prawns, and e. fish. [PBA] = The highest-quality plant-based chicken nuggets’
Will most cultured meat (by volume) be produced with hydrolysates in 2036?
Will most cultured meat (by volume) be produced with hydrolysates in 2036?
Predict-experts: Average production cost of cultured (chicken) per kg (WIP)
At [resolution date ~Dec. 2026], what will be the median of the linearly aggregated beliefs among the set of Unjournal evaluators and experts over the average production cost (per edible kg) of cultured chicken meat at the end of 2051 across all large-scale plants in the world” (I.e., for
direct question, using beliefs given on this platform.)
Linearly aggregated: Essentially, adding the pdfs (distributions) vertically and re-scaling these to sum to probability=1. This is not the standard Metaculus aggregation (see discussion here [link]).
Evaluators and experts: Any of the following people who respond to this question –
Average cost of growth factors by 2036
What will be the average cost of recombinant growth factors per gram (of input) in commercial cultured meat production in 2036?
Cell media costs in 2036
What will be the cost of cell media per kg of cultured meat in 2036?
Quantity of cell media required to produce 1kg of cultured meat in 2036
What will be the average quantity of cell media, in liters, necessary to produce 1kg of cultured meat in 2036?
Maximum cell density achieved in 20k liter bioreactor by 2036
What will be the highest cell density of cultivated meat produced in a 20,000 liter bioreactor by 2036?
Is cultured meat development a good investment from an animal welfare POV?
What is the expected-value (and probability distribution) of the impact on animal welfare from funding the development of cell-cultured meat? We could refine this question further to specifically consider: (i) marginal (aka incremental) funding, (ii) very high levels of funding, or (iii) the impact relative to the best alternative animal welfare interventions.
Food-grade vs pharmaceutical-grade cell media
By 2036, what percent of commercial cultured meat will be produced using food-grade cell media (as opposed to pharmaceutical-grade)?
Although some past sources seem to suggest that pharmaceutical-grade cell media would be necessary for safe cultured meat production, food-grade media and bioreactors seem to be the current standard. We are currently investigating whether questions of pharmaceutical-grade vs food-grade resources are still relevant.
Price of cultured meat with widespread hydrolysate use
Conditional on “most CM is produced with plant hydrolysates in 2036?”, what will be the average price of 1 kg of cultured meat?
Price of cultured meat without widespread hydrolysate use
Conditional on “most CM is NOT produced with plant hydrolysates in 2036?”, what will be the average price of 1 kg of cultured meat?
What percent of companies will build their own bioreactors by 2036?
What share of cultured meat companies (those with capex over XXX amount) will design and build their own bioreactors by 2036?
This question is based on some reports that companies can design and build their own bioreactors for a much lower cost than purchasing off-the-shelf pharmaceutical bioreactors.
How many chickens will be slaughtered for meat globally in the following years?
How many chickens will be slaughtered for meat globally in the following years?
Years: 2025, 2032, 2052, 2122
This question will resolve as the total number of chickens slaughtered for meat in the respective year for the whole world according to. For example, this figure was 70.77 billion in the year 2020.
How many metric tons of ≥51% cultured meat costing <$10/kg will be sold from 2020 to 2050?
How many metric tons of ≥51% cultured meat costing <$10/kg will be sold from 2020 to 2050?
Example: the year 2025 will resolve as the average of the years 2021, 2022, 2023, 2024, 2025.
Resolution will be via industry statistics from credible sources akin to the FAO & USDA (such as independent credible outside analysts, governments, inter-governmental agencies, the FAO itself, & The Good Food Institute's market research reports.) Evidence of the cultured meat containing a product's listing price and composition should come from credible media reports, online supermarket listings, or from at least three reports sourced from social media and/or submissions by Metaculus users/admin.
How many metric tons of ≥51% cultured meat will be sold from 2020 to 2050?
How many metric tons of ≥51% cultured meat will be sold from 2020 to 2050?
Example: the year 2025 will resolve as the average of the years 2021, 2022, 2023, 2024, 2025.
Resolution will be from industry statistics from credible sources akin to the FAO & USDA (such as independent credible outside analysts, governments, inter-governmental agencies, the FAO itself, & The Good Food Institute's market research reports.)
Largest single CM facility capacity by 2030
What will be the largest cultivated meat production capacity, in metric tons per year, of a single facility by January 1, 2030?
This question will resolves as the highest reported production capacity, in metric tons per year, of a single physical facility that produces cultivated meat products by January 1, 2030.
The following types of evidence would decide the question:
What will the lowest retail price, in USD per kg, of any product containing 50% clean meat be, in the calendar year 2029?
What will the lowest retail price, in USD per kg, of any product containing 50% clean meat be, in the calendar year 2029?
Resolution
This question resolves as the lowest reported price, in 2019 USD per kg, of any product listed in a retail supermarkets that contains at least 50% clean meat by weight. Qualifying retail supermarkets are those based in either the U.S. or based in the European Union as of August, 2019, and Switzerland.
How much revenue will the U.S. market for clean meat generate, in the fiscal year 2030, in millions of USD?
How much revenue will the U.S. market for clean meat generate, in the fiscal year 2030, in millions of USD?
Resolution:
This question resolves as a credible estimate of the revenue by companies generated from the sale of clean-meat containing products for human consumption in the U.S., in the [U.S. fiscal year](https://en.wikipedia.org/wiki/Fiscal_year#United_States) 2030. The figure shall be given in millions of USD, in 2019 prices. Qualifying products need to contain at least 1% of clean meat by weight. Clean meat is here defined as meat that is grown primarily or entirely in cell culture, rather than in an animal’s body.
(Meta) Reliability of estimating cross-price elasticities/substitution effects
Can cross-price elasticities and substitution effects be reliably and precisely estimated in a context like this?
(Meta) Type and cost of experiment to yield useful cost-price elasticity estimates
What sort of (~supermarket) experimental trial would be needed to yield useful estimates of cross-price elasticities for key PBA/~meat pairings, and how much would an informative trial cost?
(Model for goals) Cross-price elasticity threshold that justifies funding PBAs — (very optional, conditional on the Meta question about estimation)
How high a cross-price elasticity (or rate of substitution) between key products (say, plant-based beef & chicken breasts) would be necessary to justify funding R&D for PBAs?
Animal welfare benefit of plant-based meat vs best alternative Animal Welfare intervention
Does the animal welfare benefit of (having) donated $100,000 in 2026 to fund the cost reduction and availability of Impossible Burgers (and similar) via GFI exceeded the animal welfare benefit (according to your chosen metric) of having donated the same amount ? [State a probability on Metaculus]
Is PBA-research a good investment from an animal welfare POV?
Do PBAs displace animal-welfare-relevant animal-based product consumption enough to make investments in reducing their cost [and increasing their quality] plausibly competitive with other animal welfare interventions?
Alt framing:
Or ‘what probability do you assign to this’?
Predict-experts: Focal question (1 instance)
At [resolution date ~Dec. 2026], what will be the median probability of the linearly aggregated beliefs among the set of Unjournal evaluators and experts over:
“If the price of the highest-quality hamburger-imitating plant products fell by 10% everywhere, how many more/fewer chickens would be consumed globally in the year 2027 (as a +/- percent)?” — e.g., how will resolve?
Focal: Average production cost of cultured (chicken) per kg
“What will be the average production cost (per edible kg) of cultured chicken meat in the given years, expressed in value units, across all large-scale plants in the world” ...
Average Production Cost (AC): (Annualized capital charge + all operating costs) ÷ annual kilograms of edible cultured-meat output
Capital charge: From total capital investment (TCI) amortized over the plant life from a new firm that would enter this market, adjusted for market risk
Marginal Cost at Scale. While AC incorporates the capital expenditure involved in getting facilities up and running, marginal cost solely captures the cost of producing each additional kilogram of product. While these marginal costs are unlikely to reflect the sustainable market price of CM, they are important for modeling the sensitivity to market power and the nature of competition, and to considering the marginal impact of subsidies.
Average Cost Function. Careful forecasters are likely to model the relationship between costs plant capacity, and global production (e.g., a power law scaling). Explicitly stating this would help us consider how robust the AC forecast is to alternative assumptions, and to extrapolate to different scenarios.
Predict-experts: Animal welfare benefit of plant-based meat vs best alternative Animal Welfare intervention
At [resolution date ~Dec. 2026], what will be the median probability of the linearly aggregated beliefs among the set of Unjournal evaluators and experts over:
whether the animal welfare benefit of (having) donated $100,000 in 2026 to fund the cost reduction and availability of Impossible Burgers (and similar) via GFI
will have exceeded the animal welfare benefit (according to experts’ chosen metric) of having donated the same amount
Best wellbeing measure given available data
Given the available collected data from surveys and intervention trials, how should Founders’ Pledge measure the impact on wellbeing in the context of mental health interventions? E.g., should they use the WELLBY measure (as defined above) or another metric? Consider reliability, insight, and practicability.
See context and definition
What measures to collect?
What measures of well-being (or life satisfaction, or happiness, etc.) should charities, NGOs, and RCTs collect for impact analysis, particularly in contexts that may involve less tangible well-being outcomes (especially in mental health interventions)?
[Focal question] Best measure for comparing multi-outcome interventions
Which combination of (a) wellbeing-relevant data and self-reports (e.g., happiness, life-satisfaction surveys) and (b) metric based on this data (e.g., linear WELLBY units, standard deviation movements, adjustments for scale use) would be “best*” for making funding choices between interventions whose impacts may include mental health, physical health, and consumption outcomes.
[Focal question] Placeholder — we should converge on 1 focal question per PQ
Best WELLBY/DALY conversion for FP
Which mapping between WELLBYs and DALYs (or QALYs), should Founders Plege use in comparing XYZ in order to make decisions between charities like X and Y; the mapping yielding with the highest expected value decisionmaking [for some chosen measure of welfare]?
A specific scale use question?
“Is the scale use problem so grave that it makes WELLBY use worse than XXX”
Loss from SD-SD conversion
What is the loss from the “one SD change in WELLBY is equivalent to one SD change in DALY” approach that FP is currently taking relevant to the best feasible approach? Where will their approach be particularly incorrect?

The table below explains each of these ‘question type’ categories.
Question type
Description of question type
PQ for evaluation
The focal pivotal question that PQ-evaluators should prioritize.
Goal-oriented
These address the broader or more actionable questionof direct interest to partner organizations. Generally less tractable for direct evaluation, but worth keeping in mind.
Metaculus
Posted/to be posted in our (a prediction platform) and potentially in Metaculus main stream. PQ- evaluators and our experts & stakeholder team should state their beliefs on the platform and share their ID with us. Other question types may also be given this tag if they are posted on Metaculus.
Candidate PQ
Not official yet. ~For internal discussion.
Subquestion or building-block
Secondary questions PQ-evaluators should address, if they have capacity. Some of these may be ‘key factors’ informing the “PQ for evaluation”. Others may be adjacent PQs that are also high-value (but prioritized slightly below the ‘PQ for evaluation’).
There are no rows in this table

Goal-focused questions: These explain the actionable goal of the question writ large. Not easy to evaluate, but worth bearing in mind.
