Fluid vs Crystallized Intelligence in AI

Key Points

  • The quiz distinguishes between crystallized intelligence (recalling known facts like “Paris is the capital of France”) and fluid intelligence (using reasoning to solve novel problems such as completing a sequence).
  • Crystallized intelligence relies on accumulated knowledge and experience, while fluid intelligence is the ability to think logically and solve unfamiliar challenges independent of prior learning.
  • Psychologist Raymond Cattell first formalized the concepts of fluid and crystallized intelligence in 1963.
  • Both forms of intelligence are relevant to AI: systems like IBM Watson use crystallized intelligence to retrieve factual answers, and combine fluid intelligence to interpret context, personalize recommendations, and solve complex, unfamiliar tasks such as generating a customized travel itinerary.

0:00pop quiz time let's test your 0:04intelligence so 0:06what is the capital of france 0:10why paris may we 0:13okay now complete the sequence 0:16a1 0:18b2 0:19c 0:20did you say three 0:23yeah that's pretty easy but that wasn't 0:26the real quiz here's what i really want 0:28to know 0:29which form of thinking did you use to 0:32solve each question 0:34well recalling previously acquired 0:36information like a capital city is a 0:38form of intelligence 0:40known as crystallized intelligence 0:47whereas the use of reasoning and logic 0:51to deduce the next character in a 0:53sequence 0:54that is known as fluid 0:58intelligence 1:00my name is martin keane and i'm a master 1:02inventor at ibm so crystallized 1:05intelligence refers to knowledge that 1:08comes from previously acquired 1:11information 1:18it's dependent on a person's knowledge 1:20on their skills on their expertise 1:23developed over a lifetime of learning 1:25and experience crystallized intelligence 1:28is fact 1:29and experience based 1:34whereas fluid intelligence is the 1:36capacity to think logically and solve 1:39problems in new and unfamiliar 1:41situations independent of acquired 1:43knowledge 1:44fluid intelligence represents a person's 1:46ability to problem-solve using reasoning 1:53and by also using 1:55logic 2:00when you come across a new problem that 2:02your current knowledge can't address you 2:04call on fluid intelligence to resolve it 2:07now 2:08the notion of fluid and crystallized 2:10intelligence dates back to 1963 2:14when it was first formalized by 2:16psychologist raymond cattell 2:22now you might be asking yourself 2:26why am i 2:28talking about psychology in an ibm 2:31technology video well 2:34because these two forms of intelligence 2:37that we use to solve problems every day 2:39can also play an important role in 2:42machine learning so for example consider 2:45an ai system like ibm watson to answer a 2:47question it can sift through like a 2:49million books per second and perhaps the 2:52answer to a question is right there in 2:54one of those books like our paris 2:56example 2:58in that case it's a simple case of 2:59natural language understanding to answer 3:02the question what is the capital of 3:03france that's crystallized intelligence 3:06but most problems aren't that simple and 3:10to solve them we may need to combine 3:12both crystallized and fluid intelligence 3:15together 3:17so for example say we wanted an a i 3:20travel system 3:22let's build one 3:25an ai travel system and what we want it 3:28to do 3:30is to build us an itinerary of the best 3:34way to spend a day in paris so the 3:36output of this 3:38is an itinerary 3:42we need to use our knowledge of parisian 3:45geography and cultural history to build 3:48a corpus of what's available 3:56that's the crystallized intelligence 3:57part but we also need to apply those 4:01options to a derived understanding of 4:04the types of activities that we like to 4:08do 4:13so these are the sorts of things that 4:14we'd be interested in doing what do we 4:16normally do when we visit a new city are 4:18there comparable options here in paris 4:22can we tailor this to our personality to 4:24our budget and our willingness to try 4:26new things all of that stuff well that's 4:28the fluid intelligence side of things 4:31so from there a system could derive a 4:34subset of all the possible things to do 4:37in paris that day distilled into a 4:40tailorized personalized 4:42itinerary 4:45so for us humans our crystallized 4:47intelligence is knowledge we acquire and 4:50fluid intelligence is how we apply it 4:52for an ai system you can think of a 4:54systems model as being crystallized 4:56intelligence because it teaches itself 4:59to do one task really well by training 5:02on massive data sets of prior experience 5:05then you can think of its ability to 5:07solve new problems as being fluid 5:10intelligence because it can 5:11apply that model to a previously unseen 5:14problem 5:16and as for me 5:18my crystallized and fluid intelligence 5:20is telling me that 5:21morning croissants under the eiffel 5:23tower 5:24should be top of my list 5:28if you have any questions please drop us 5:29a line below and if you want to see more 5:32videos like this in the future please 5:34like and subscribe 5:35thanks for watching
