  • I appreciate your passion for scientific literacy - it’s crucial for combating misinformation. However, I’d like to share some perspectives that might broaden our understanding of scientific knowledge and how it develops.

    First, it’s worth noting that the distinction between “theory” and “hypothesis” isn’t as clear-cut as we might think. In “The Scientific Attitude,” Stephen McIntyre argues that what truly defines science isn’t a rigid set of rules, but rather an ethos of critical inquiry and evidence-based reasoning. This ties into the “demarcation problem” in philosophy of science - the challenge of clearly defining what is and isn’t science. Despite this ongoing debate, science continues to be a powerful tool for understanding our world.

    Your stance seems to align with positivism, which views scientific knowledge as objective and verifiable. However, other epistemological approaches exist. Joseph A. Maxwell’s work on critical realism offers a nuanced view that acknowledges both the existence of an objective reality and the role of human interpretation in understanding it.

    Maxwell defines validity in research not just as statistical significance, but as the absence of plausible alternative explanations. This approach encourages us to constantly question and refine our understanding, rather than treating any explanation as final.

    Gerard Delanty’s “Philosophies of Social Science” provides a historical perspective on how our conception of science has evolved. Modern views often see science as a reflexive process, acknowledging the role of the researcher and societal context in shaping scientific knowledge.

    Larry McEnery’s work further emphasizes this point, describing how knowledge emerges from ongoing conversations within communities of researchers. What we consider “knowledge” at any given time is the result of these dynamic processes, not a static, unchanging truth.

    Understanding these perspectives doesn’t diminish the power or importance of science. Instead, it can make us more aware of the complexities involved in scientific inquiry and more resistant to overly simplistic arguments from science deniers.

    By embracing some psychological flexibility around terms like “theory” and “hypothesis,” we’re not opening the door to pseudoscience. Rather, we’re acknowledging the nuanced nature of scientific knowledge and the ongoing process of inquiry that characterizes good science.

    What do you think about these ideas? I’d be interested to hear your perspective and continue this conversation.


  • Thanks for the response. I guess I do see much of human behavior through a contextual behaviorist lens. Sorry if it seems excessive. I am not Hayes or Hoffman. It is just frustrating to see blanket explanations for human behavior, instead of understanding specific processes. I guess I really want to avoid the fundamental attribution error and reductionism, something contextual behaviorism deliberately aims to avoid.

    While I recognize Emotion Focused Therapy is helpful to understand and, if possible, change social behavior (which is why I mentioned it previously), I maybe should have brought up Emption Construction Theory or even Sapolsky’s multi-lens framework, considering different timescales of explanation. Would you have suggested something different? When does contextual behaviorism fail?

    Thanks for helping me potentially falling into reductionism. I wouldn’t want to fall in that trap.





  • I agree that we shouldn’t jump immediately to AI-enhancing it all. However, this survey is riddled with problems, from selection bias to external validity. Heck, even internal validity is a problem here! How does the survey account for social desirability bias, sunk cost fallacy, and anchoring bias? I’m so sorry if this sounds brutal or unfair, but I just hope to see less validity threats. I think I’d be less frustrated if the title could be something like “TechPowerUp survey shows 84% of 22,000 respondents don’t want AI-enhanced hardware”.





  • Agile is indeed more of a mindset than a rigid system. In my recent experience helping a tabletop game team, we applied Agile principles to great effect. Rather than trying to perfect every aspect of the game at once, we focused on rapidly iterating the core mechanics based on player feedback. This allowed us to validate the fundamental concept quickly before investing time in peripheral elements like the looks of the game.

    This approach embodies the Agile value of ‘working product over comprehensive documentation’ - or in our case, ‘playable game over polished components’. By prioritizing what matters most to players right now, we’re able to learn and adapt much more efficiently.

    Agile thinking helps us stay flexible and responsive, whether we’re developing software or board games. It’s about delivering value incrementally and being ready to pivot based on real-world feedback.


  • I appreciate your candor about not wanting to speak on topics outside your expertise. That’s commendable. I wonder if we can still talk with the understanding that we may not know it all. I truly believe curiosity is able to sidestep many of the problems related with ignorance.

    You’re right to be cautious about appeals to authority. My intention wasn’t to suggest NASA’s use of Agile validates it universally, but rather to counter the OP comic’s implication that Agile is inherently incapable of achieving significant goals like space exploration.

    Regarding Agile-like practices in earlier NASA projects, you’re correct that concrete evidence is limited. However, we can analyze their approaches through the lens of Agile principles. Scrum, for instance, aims to foster characteristics found in high-performing teams: clear goals, information saturation, rapid feedback loops, adaptability to changing requirements, and effective collaboration. These elements aren’t exclusive to Scrum or even to modern Agile methodologies. The key is recognizing that effective project management often naturally gravitates towards these principles, whether formally adopting Agile or not.

    It’s an interesting area for further research: have complex engineering projects historically incorporated elements we now associate with Agile? If so, how?

    Your skepticism is valuable in pushing for a more nuanced understanding of project management across different domains.


  • You’ve got a good point. I wonder if this an example of a trade-off between convenience and security. If you’re logging in and you get an MFA prompt, a Yubikey has to be physically searched, while Bitwarden or Proton Pass only have to be clicked. A Yubikey can only hold a limited amount of accounts, while Bitwarden or Proton Pass could hold many more. Of course, a Yubikey could be used as MFA for Bitwarden or Proton Pass, but that would create a single point of failure and reduce factor separation (which I think is your original point).

    While I posted a Bitwarden or Proton Pass recommendation of sorts, I genuinely wonder if it’s advisable to not use MFA at all if the factors will not be separated. Or, perhaps, the best security solution is the one you’ll actually use. I guess the answer is the good ol’ “What’s your security model?”



  • I can see you’re frustrated by the downvotes and pushback you’ve received. It’s understandable to feel defensive when your viewpoint isn’t well-received. I appreciate you sharing your perspective, even if it goes against the majority opinion here.

    Your points about the space shuttle program’s challenges are valid and worth discussing. It’s important to note the timeframes involved though. The shuttle was developed in the 1970s, well before agile methodologies emerged in the 1990s and 2000s.

    Interestingly, one could argue that NASA may have used agile-like practices in the space shuttle program, even if they weren’t labeled as such at the time. However, I did a quick search and couldn’t find much concrete evidence to support this idea. It’s an intriguing area that might merit further research.

    Regarding modern agile approaches, while no method is perfect, many organizations have found them helpful for improving flexibility and delivering value incrementally. NASA’s recent use of agile for certain projects shows they’re open to evolving their methods.

    I’m curious to hear more about your thoughts on software development approaches for complex engineering projects. What do you see as the pros and cons of different methodologies? Your insights could add a lot to this discussion.



  • Your comparison is interesting, but let’s consider some historical facts. The Apollo program, which successfully put humans on the moon, actually employed many principles we now associate with Agile methodologies.

    Contrary to popular belief, it wasn’t a straightforward Waterfall process. NASA used frequent feedback (akin to daily Scrums), self-organizing teams, stable interfaces so that teams are an independent path to production, and iterative development cycles - core Agile practices. In fact, Mariana Mazzucato’s book Mission Economy provides fascinating insights into how the moon landing project incorporated elements remarkably similar to modern Agile approaches. Furthermore, here’s a NASA article detailing how Agile practices are used to send a rover to the moon: https://ntrs.nasa.gov/api/citations/20160006387/downloads/20160006387.pdf?attachment=true

    While it’s true that building rockets isn’t identical to software development, the underlying principles of flexibility, collaboration, and rapid iteration proved crucial to the missions’ success. Programs like the Apollo program adapted constantly to new challenges, much like Agile teams do today.

    Regarding Kanban and Scrum, you’re right that they fall under the Agile umbrella. However, each offers unique tools that can be valuable in different contexts, even outside of software.

    Perhaps instead of dismissing Agile outright for hardware projects, we could explore how its principles might be adapted to improve complex engineering endeavors. After all, if it helped us reach the moon and, decades later, send rovers to it, it might have more applications than we initially assume.
