Quotes About Hypothesis

For the growth hypothesis, which tests how new customers will discover a product or service, we can do a similar analysis.

I call the riskiest elements of a startup's plan, the parts on which everything depends, leap-of-faith assumptions. The two most important assumptions are the value hypothesis and the growth hypothesis.

Everything that has been discussed so far is a prelude to a seemingly simple question: are we making sufficient progress to believe that our original strategic hypothesis is correct, or do we need to make a major change? That change is called a pivot: a structured course correction designed to test a new fundamental hypothesis about the product, strategy, and engine of growth.

Second, when an entrepreneur has an unclear hypothesis, it's almost impossible to experience complete failure, and without failure there is usually no impetus to embark on the radical change a pivot requires.

Compare two startups. The first company sets out with a clear baseline metric, a hypothesis about what will improve that metric, and a set of experiments designed to test that hypothesis. The second team sits around debating what would improve the product, implements several of those changes at once, and celebrates if there is any positive increase in any of the numbers. Which startup is more likely to be doing effective work and achieving lasting results?

are we making sufficient progress to believe that our original strategic hypothesis is correct, or do we need to make a major change?

The word pivot sometimes is used incorrectly as a synonym for change. A pivot is a special kind of change designed to test a new fundamental hypothesis about the product, business model, and engine of growth.

We had gotten really good at optimizing, tuning, and iterating, but in the process we had lost sight of the purpose of those activities: testing a clear hypothesis in the service of the company's vision. Instead, we were chasing growth, revenue, and profits wherever we could find them.

Thus, it is not the customer, but rather our hypothesis about the customer, that pulls work from product development and other functions. Any other work is waste.

A pivot is not just an exhortation to change. Remember, it is a special kind of structured change designed to test a new fundamental hypothesis about the product, business model, and engine of growth. It is the heart of the Lean Startup method. It is what makes the companies that follow Lean Startup resilient in the face of mistakes: if we take a wrong turn, we have the tools we need to realize it and the agility to find another path.

retrospective studies are well suited for generating a hypothesis, then the hypothesis can be tested prospectively and supported, especially when independently replicated.

The modern scientific method in which experiments form part of a structured system of hypothesis, experimentation, and analysis is as recent as the seventeenth century; the problem-solving technology of cooking goes back thousands of years.

A)ny working hypothesis was probably going to involve quantum theory at some point—the part of physics that made my brains trickle out of my ears.

I'm working on several theories," I said. "But I'm currently favoring the hypothesis that the moon has a seemingly arbitrary effect on magic because it likes to piss me off." "That's a theory with a high degree of applicability to other spheres of life," he said. "Yes it is," I said, and we spontaneously fist

The timing alone argues against that hypothesis.

Some economists, when thinking about long memory, are concerned that it undercuts the Efficient Market Hypothesis that prices fully reflect all relevant information; that the random walk is the best metaphor to describe such markets; and that you cannot beat such an unpredictable market. Well, the Efficient Market Hypothesis is no more than that, a hypothesis. Many a grand theory has died under the onslaught of real data.

I maintain that it is a very odd place to look. What that's called is a singularity, and many theories require a singularity. That means to kick start the intellectual engine you have to go outside the system, and you get one free hypothesis and then once you have used that up your system has to run very very smoothly clear down to the end.

Right. Isn't that how science works?" Redwing grinned. "If you don't understand, do an experiment.

Riemann conjecture

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.

Evolution is not truth; it is merely a hypothesis-it is millions of guesses strung together.

Science is a combination of theory and experiment and the two together are how you make progress.

Emilio] felt once more the strangely visceral thrill of trying to disprove a hypothesis he suspected was robust.

Karl Popper – that any theory that is incapable of falsification cannot be considered scientific.
