In an essay I wrote, "only unaware practitioners use made-up #personas in their design work".

I think I know why this is done.

There is a difference between #characters and #archetypes. You can make up characters, as long as each character is based on a researched archetype.

People who make up personas are actually making up characters, but they make these characters without any grounding. There are usually no researched archetypes.

You can do better, and have fun:

"Argument-Making in the Wild"

Today's SFI Seminar by Simon DeDeo (@LaboratoryMinds), streaming now. Follow our thread for pull quotes and slides:

First, let's divide human history into three eras, or regimes of #knowledge #production and #consumption:

• #premodern/#archaic
• #modern + #postmodern
• the #egregore (online content sharing)

• The premodern era is defined by caloric restriction.
• The modern era is characterized by a small number of sellers of #information vs. a large number of consumers (see also #HerbertSimon's remarks on the "poverty of #attention")

Your Safety and You.


As at time of the accident it wasn't clear the number of persons trapped for easy evacuation and rescue.

1. Develop a manifest/register at work sites and offices

2. Make use of T-cards for everyone working/visiting your sites/offices Image

The cost of safety can't be equated to the cost of ignorance. "I don't care" na person wey e never reach him side.

Don't wait until it happens, stop been reactive be proactive. The rate of building collapse might be on the increase and until people are held
accountable for cutting corners we are not sure these will end anytime soon.

Your looking the other way when processes and procedures are violated makes you an accomplice to whatever eventually happens If you see something!

So, 30 hours of battery storage for $660 / kW comes down to $22 / kWh.

That's less than one tenth of the cost of today's leading $300 / kWh Tesla "Megapack" utility battery storage product. 🤔

Why am I challenging Dr. Clack?

Because he is selling antinuclear have-your-cake-and-eat-it renewable energy studies that he asserts "find" least-cost energy systems with little or no nuclear energy, while in fact he simply assumes it, hidden in the fine print of his papers.
Note how I try to evaluate Clacks storage cost assumption by comparing to the *best* current storage cost quote I could find.

In his effort to support his nuclear cost assumptions, he refers to the *worst* project he could find.

This is not fine.

1/6 Excited to share our new #biologicalconservation paper on the #illegalwildlifetrade of #jaguars in #Belize and #Guatemala by @EJMilnerGulland @orchiddelirium and myself, in partnership with @WCS_Mesoamerica. Free access for a limited time at:… Image
2/6 Based on key informant interviews, we found that #jaguartrade is a #domestic and #opportunistic activity, driven by local actors for a range of #motivations, and with ties to #humanwildlifeconflict, #bushmeathunting, #Chinesedemand, #drugtrafficking, #migration and #tourism Image
3/6 By separating statements into well #evidenced examples vs. #assumptions, we found that the areas of higher #uncertainty in the #jaguartrade include the role of external actors and drivers, and of commercial motivations. Image
