There is no definitive answer to whether intelligence is decreasing overall. Some studies suggest that average IQ scores have been increasing over time, a phenomenon known as the Flynn effect. However, other research indicates that certain cognitive abilities may be declining due to factors such as environmental pollution, lifestyle changes, and decreased physical activity. It is important to consider multiple factors and perspectives when evaluating trends in intelligence levels. **

It is difficult to determine if the quality is decreasing without specific context or criteria to evaluate. Quality can be subjective and dependent on individual preferences or standards.

Strictly monotonically decreasing/increasing means that the function is continuously decreasing/increasing without any flat regions or plateaus. On the other hand, monotonically decreasing/increasing allows for the function to have flat regions or plateaus where the function remains constant before continuing to decrease/increase. In essence, strictly monotonically decreasing/increasing is a more stringent condition compared to monotonically decreasing/increasing. **

Strictly monotonic decreasing/increasing means that the function is either always decreasing or always increasing, without any flat regions or plateaus. Monotonic decreasing/increasing, on the other hand, allows for flat regions where the function remains constant. In other words, strictly monotonic functions do not have any horizontal sections, while monotonic functions may have horizontal sections. **

Strictly monotonic increasing/decreasing means that the function is either always increasing or always decreasing, without any flat regions or plateaus. Monotonic increasing/decreasing, on the other hand, allows for the possibility of flat regions or plateaus where the function remains constant. In other words, strictly monotonic functions do not have any horizontal sections, while monotonic functions may have some. **
